    Standards for information security and processes in healthcare2009Inngår i: Journal of Systems and Information Technology, ISSN 1328-7265, E-ISSN 1758-8847, Vol. 11, nr 3, s. 295-308Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose - Regardless of who or where we are and when we get sick, we expect healthcare to make us well and to handle us and our information with care and respect. Today, most healthcare institutions work separately, making the flow of patient information sub-optimal and the use of common standards practically unheard of. The purpose of this paper is to emphasise the use of standards to improve information security in process-oriented distributed healthcare. Design/methodology/approach - The paper introduces a real-life case which is analysed to highlight how and where standards can and should be used in order to improve information security in process-oriented distributed healthcare. Findings - In total, 11 flaws or problems in information security and process-orientation are identified. From these, six changes are suggested which address how information is handled, and how organizational routines should be standardized. Research limitations/implications - The case setting is Swedish healthcare, but problems can be shared across international borders. The purpose is to highlight the issues at hand. Practical implications - If suggested changes are implemented, healthcare processes will be more streamlined and focused on patients. Routines will be standardized and uncertainties thus removed in terms of how to act in certain situations. Originality/value - Healthcare and academia has yet to address both document and process issues concerning standardization in distributed healthcare. There are also few actual cases from a patient perspective. This paper provides lessons learned from a real-life case, where results may impact how standardization is addressed in healthcare organizations.

    Trusting Digitized Patient-Related Information: The Need for a New Approach2011Inngår i: Proceedings of the 5th International Symposium on Human Aspects of Information Security and Assurance (HAISA 2011) / [ed] Steven Furnell, Nathan Clarke, Plymouth Center for Security, Comunications & Network Research, University of Plymouth , 2011, s. 119-129Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Trust the receiving increasing attention nowadays, particularly since new technology enables communication and collaboration like it has never been seen before. However, trust is a fuzzy concept that needs further examination and attention from multiple levels. For examples, security is very important from a user's point of view in trusting that technology will function in accordance with the user's intended and requested function. This paper reviews the concept of patient safety, which thus far has been discussed and defined from a narrow technical perspective. We demonstrate that it is much more complex, and that it is not primarily the technical issues that are problematic, but rather the cultural, process-related and personnel issues. Our results point to a need for a new approach, which takes the patient's view of healthcare and the patient-related digital information as its focus. The discussion is made from a Swedish perspective, but the issues are international. The needs for information and knowledge in healthcare are obvious. Without clear definitions of concepts and roles, a good information flow or process cannot be designed. Our discussion shows that trusted digital patient information gives an opportunity for a patient-focused healthcare. Multidimensional trust must be addressed on all levels; organization, person and technology. More empirical research into trust in digital patient-related information is necessary, to develop a model for patient safety from a trust perspective that encompasses all levels of trust.

    Comprehensible Models for Predicting Molecular Interaction with Heart-Regulating Genes2008Inngår i: Proceedings of the Seventh International Conference on Machine Learning and Applications, IEEE Computer Society, 2008, s. 559-564Konferansepaper (Fagfellevurdert)
    Abstract [en]

     When using machine learning for in silico modeling, the goal is normally to obtain highly accurate predictive models. Often, however, models should also bring insights into interesting relationships in the domain. It is then desirable that machine learning techniques have the ability to obtain small and transparent models, where the user can control the tradeoff between accuracy, comprehensibility and coverage. In this study, three different decision list algorithms are evaluated on a data set concerning the interaction of molecules with a human gene that regulates heart functioning (hERG). The results show that decision list algorithms can obtain predictive performance not far from the state-of-the-art method random forests, but also that algorithms focusing on accuracy alone may produce complex decision lists that are very hard to interpret. The experiments also show that by sacrificing accuracy only to a limited degree, comprehensibility (measured as both model size and classification complexity) can be improved remarkably.

    Agents without Agency?2007Inngår i: Cognitive Semiotics, ISSN 1662-1425, Vol. 0, nr 1, s. 102-124Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The notion of agency occupies a central position in several of the

    cognitive sciences, particularly artificial intelligence (AI) and robotics. However, the notion largely rests on folk psychology and is usually left more or less undefined. This paper examines different notions of agency and analyzes the concept with a special focus on its role in AI, where much recent research has been devoted to the construction of artificial agents. We highlight recent naturalist theories of agency and argue that even if agency is not merely a folk-psychological concept without ontological bearing or scientific value, the phenomenon is more complex than most theories acknowledge. We argue that, as the title implies, none of the so-called agents of contemporary AI and robotics can be attributed agency in the strong sense, although artificial agency is not impossible in principle.

    High-Performance Computing For Support Vector Machines2018Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Machine learning algorithms are very successful in solving classification and regression problems, however the immense amount of data created by digitalization slows down the training and predicting processes, if solvable at all. High-Performance Computing(HPC) and particularly parallel computing are promising tools for improving the performance of machine learning algorithms in terms of time. Support Vector Machines(SVM) is one of the most popular supervised machine learning techniques that enjoy the advancement of HPC to overcome the problems regarding big data, however, efficient parallel implementations of SVM is a complex endeavour. While there are many parallel techniques to facilitate the performance of SVM, there is no clear roadmap for every application scenario. This thesis is based on a collection of publications. It addresses the problems regarding parallel implementations of SVM through four research questions, all of which are answered through three research articles. In the first research question, the thesis investigates important factors such as parallel algorithms, HPC tools, and heuristics on the efficiency of parallel SVM implementation. This leads to identifying the state of the art parallel implementations of SVMs, their pros and cons, and suggests possible avenues for future research. It is up to the user to create a balance between the computation time and the classification accuracy. In the second research question, the thesis explores the impact of changes in problem size, and the value of corresponding SVM parameters that lead to significant performance. This leads to addressing the impact of the problem size on the optimal choice of important parameters. Besides, the thesis shows the existence of a threshold between the number of cores and the training time. In the third research question, the thesis investigates the impact of the network topology on the performance of a network-based SVM. This leads to three key contributions. The first contribution is to show how much the expansion property of the network impact the convergence. The next is to show which network topology is preferable to efficiently use the computing powers. Third is to supply an implementation making the theoretical advances practically available. The results show that graphs with large spectral gaps and higher degrees exhibit accelerated convergence. In the last research question, the thesis combines all contributions in the articles and offers recommendations towards implementing an efficient framework for SVMs regarding large-scale problems.

    Parallel Computing of Support Vector Machines: A Survey2019Inngår i: ACM Computing Surveys, ISSN 0360-0300, E-ISSN 1557-7341, Vol. 51, nr 6, s. 123:1-123:38, artikkel-id 123Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    The immense amount of data created by digitalization requires parallel computing for machine-learning methods. While there are many parallel implementations for support vector machines (SVMs), there is no clear suggestion for every application scenario. Many factor—including optimization algorithm, problem size and dimension, kernel function, parallel programming stack, and hardware architecture—impact the efficiency of implementations. It is up to the user to balance trade-offs, particularly between computation time and classification accuracy. In this survey, we review the state-of-the-art implementations of SVMs, their pros and cons, and suggest possible avenues for future research.

    Empirical Study of Time Efficiency and Accuracy of Support Vector Machines Using an Improved Version of PSVM2015Inngår i: Proceedings of the 2015 International Conference on Parallel and Distributed Processing Techniques and Applications: PDPTA 2015: Volume 1 / [ed] Hamid R. Arabnia, Hiroshi Ishii, Kazuki Joe, Hiroaki Nishikawa, Havaru Shouno, Printed in the United States of America: CSREA Press, 2015, Vol. 1, s. 177-183Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We present a significantly improved implementation of a parallel SVM algorithm (PSVM) together with a comprehensive experimental study. Support Vector Machines (SVM) is one of the most well-known machine learning classification techniques. PSVM employs the Interior Point Method, which is a solver used for SVM problems that has a high potential of parallelism. We improve PSVM regarding its structure and memory management for contemporary processor architectures. We perform a number of experiments and study the impact of the reduced column size p and other important parameters as C and gamma on the class-prediction accuracy and training time. The experimental results show that there exists a threshold between the number of computational cores and the training time, and that choosing an appropriate value of p effects the choice of the C and gamma parameters as well as the accuracy.

    Folk-Psychological Interpretation of Human vs. Humanoid Robot Behavior: Exploring the Intentional Stance toward Robots2017Inngår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 8, artikkel-id 1962Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    People rely on shared folk-psychological theories when judging behavior. These theories guide people's social interactions and therefore need to be taken into consideration in the design of robots and other autonomous systems expected to interact socially with people. It is, however, not yet clear to what degree the mechanisms that underlie people's judgments of robot behavior overlap or differ from the case of human or animal behavior. To explore this issue, participants (N = 90) were exposed to images and verbal descriptions of eight different behaviors exhibited either by a person or a humanoid robot. Participants were asked to rate the intentionality, controllability and desirability of the behaviors, and to judge the plausibility of seven different types of explanations derived from a recently proposed psychological model of lay causal explanation of human behavior. Results indicate: substantially similar judgments of human and robot behavior, both in terms of (1a) ascriptions of intentionality/controllability/desirability and in terms of (1b) plausibility judgments of behavior explanations; (2a) high level of agreement in judgments of robot behavior -(2b) slightly lower but still largely similar to agreement over human behaviors; (3) systematic differences in judgments concerning the plausibility of goals and dispositions as explanations of human vs. humanoid behavior. Taken together, these results suggest that people's intentional stance toward the robot was in this case very similar to their stance toward the human.

    Considerations for a Neuroscience-Inspired Approach to the Design of Artificial Intelligent Systems2011Inngår i: Proceedings of the Fourth Conference on Artificial General Intelligence / [ed] Schmidhuber, J. et al, Springer, 2011, s. 247-254Konferansepaper (Fagfellevurdert)
    Abstract [en]

    When designing artificial intelligent systems, one could do worse, at first glance, than take inspiration from the system whose performance one tries to match: the human brain. The continuing failure to produce such an inspired system is usually blamed on the lack of computational power and/or a lack of understanding of the neuroscience itself. This does not, however, affect the fundamental interest in neuroscience as studying the only known mechanism to date to have produced an intelligent system.

    This paper adds another consideration (to the well-established observation that our knowledge of how the brain works is sketchy at best) which needs to be taken into account when taking inspiration from neuroscience: the human brain has evolved specifically to serve the human body under constraints imposed by both the body and biological limitations. This does not necessarily imply that it is futile to consider neuroscience in such endeavours; however, this paper argues that one has to view results of neuroscience from a somewhat different perspective to maximise their utility in the creation of artificial intelligent systems and proposes an explicit separation of neural processes into three categories.

    What we need from an embodied cognitive architecture2019Inngår i: Cognitive Architectures / [ed] Maria Isabel Aldinhas Ferreira, João Silva Sequeira, Rodrigo Ventura, Cham: Springer, 2019, s. 43-57Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [en]

    Given that original purpose of cognitive architectures was to lead to a unified theory of cognition, this chapter considers the possible contributions that cognitive architectures can make to embodied theories of cognition in particular. This is not a trivial question since the field remains very much divided about what embodied cognition actually means, and we will see some example positions in this chapter. It is then argued that a useful embodied cognitive architecture would be one that can demonstrate (a) what precisely the role of the body in cognition actually is, and (b) whether a body is constitutively needed at all for some (or all) cognitive processes. It is proposed that such questions can be investigated if the cognitive architecture is designed so that consequences of varying the precise embodiment on higher cognitive mechanisms can be explored. This is in contrast with, for example, those cognitive architectures in robotics that are designed for specific bodies first; or architectures in cognitive science that implement embodiment as an add-on to an existing framework (because then, that framework is by definition not constitutively shaped by the embodiment). The chapter concludes that the so-called semantic pointer architecture by Eliasmith and colleagues may be one framework that satisfies our desiderata and may be well-suited for studying theories of embodied cognition further.

    Flexible sequence learning in a SOM model of the mirror system2012Inngår i: Building Bridges Across Cognitive Sciences Around the World: Proceedings of the 34th Annual Meeting of the Cognitive Science Society, Sapporo, Japan, August 1-4, 2012 / [ed] Naomi Miyake, David Peebles & Richard P. Cooper, Austin, TX: Cognitive Science Society, Inc., 2012, s. 2423-2428Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We present initial work on a biologically and cognitively inspired model that may allow embodied agents to autonomously learn sequences of action primitives (forming an overall behaviour). Specifically, we combine a flexible model of sequence generation with a model  of parietal mirror neuron activity. The main  purpose is to illustrate that the approach is viable. Although further work is needed to improve the results sketched out here, the concept is sound and relevant both to efforts in modelling mirror neuron activity and enabling artificial embodied agents to autonomously learn sequences of action primitives.

    Theories and computational models of affordance and mirror systems: An integrative review2013Inngår i: Neuroscience and Biobehavioral Reviews, ISSN 0149-7634, E-ISSN 1873-7528, Vol. 37, nr 3, s. 491-521Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Neuroscientific and psychological data suggest a close link between affordance and mirror systems in the brain. However, we still lack a full understanding of both the individual systems and their interactions. Here, we propose that the architecture and functioning of the two systems is best understood in terms of two challenges faced by complex organisms, namely: (a) the need to select among multiple affordances and possible actions dependent on context and high-level goals and (b) the exploitation of the advantages deriving from a hierarchical organisation of behaviour based on actions and action-goals. We first review and analyse the psychological and neuroscientific literature on the mechanisms and processes organisms use to deal with these challenges. We then analyse existing computational models thereof. Finally we present the design of a computational framework that integrates the reviewed knowledge. The framework can be used both as a theoretical guidance to interpret empirical data and design new experiments, and to design computational models addressing specific problems debated in the literature. © 2013 Elsevier Ltd.

    Prediction of human action segmentation based on end-effector kinematics using linear models2011Inngår i: European Perspectives on Cognitive Science: Proceedings of the European Conference on Cognitive Science / [ed] Kokinov, B. et al., Sofia: New Bulgarian University Press , 2011, s. 6 sidor-Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The work presented in this paper builds on previous research which analysed human action segmentation in the case of simple object manipulations with the hand (rather than larger-scale actions). When designing algorithms to segment observed actions, for instance to train robots by imitation, the typical approach involves non-linear models but it is less clear whether human action segmentation is also based on such analyses. In the present paper, we therefore explore (1) whether linear models built from observed kinematic variables of a human hand can accurately predict human action segmentation and (2) what kinematic variables are the most important in such a task. In previous work, we recorded speed, acceleration and change in direction for the wrist and the tip of each of the five fingers during the execution of actions as well as the segmentation of these actions into individual components by humans. Here, we use this data to train a large number of models based on every possible training set available and find that, amongst others, the speed of the wrist as well as the change in direction of the index finger were preferred in models with good performance. Overall, the best models achieved R2 values over 0.5 on novel test data but the average performance of trained models was modest. We suggest that this is due to a suboptimal training set (which was not specifically designed for the present task) and that further work be carried out to identify better training sets as our initial results indicate that linear models may indeed be a viable approach to predicting human action segmentation.

    The apparent intelligence of a system as a factor in situation awareness2014Inngår i: 2014 IEEE International Inter-Disciplinary Conference on Cognitive Methods in Situation Awareness and Decision Support (CogSIMA), IEEE Communications Society, 2014, s. 52-58Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In the context of interactive and automated vehicles, driver situation awareness becomes an increasingly important consideration for future traffic systems, whether it concerns the current status of the vehicle or the surrounding environment. Here, we present a simulator study investigating whether the apparent intelligence - i.e. intelligence as perceived by the driver, which is distinct from how intelligent a designer might think the system is - of a vehicle is a factor in the expectations and behaviour of the driver. We are specifically interested in perceived intelligence as a factor in situation awareness. To this end, the study modulates both traffic conditions and the type of navigational assistance given in a goal-navigation task to influence participant's perception of the system. Our result show two distinct effects relevant to situation awareness: 1) Participants who think the vehicle is highly intelligent spend more time glancing at the surrounding environment through the left door window than those who rank intelligence low and 2) participants prefer an awareness of why the navigation aid decided for specific directions but are sensitive to the manner it is presented. Our results have broader implications for the design of future automated systems in vehicles.

    A computational model of cognitive interference without neural inhibitory mechanisms2010Inngår i: Cognition in Flux: Proceedings of the 32nd Annual Meeting of the Cognitive Science Society / [ed] Stellan Ohlsson, Richard Catrambone, Austin: Cognitive Science Society, Inc., 2010, s. 1607-1612Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Interference between one cognitive behavior or sensory stimulus and subsequent behaviors is a commonly observed effect in the study of human cognition and Psychology. Traditional connectionist approaches explain this phenomenon by mutually inhibiting neural populations underlying those behaviors. Here, we present an alternative model, relying on a more detailed use of synaptic dynamics, in which populations of purely excitatory neurons can nonetheless interfere with each other, causing inhibition of activation for a varying amount of time. The fundamental, biologically motivated, mechanism in the model relies on current “spilling over” from an active neural population into another one, thereby depleting the latter population’s synaptic resources. The principles underlying the model may find applications even in the design of problemsolving artificial neural networks.

    On the functional contributions of emotion mechanisms to (artificial) cognition and intelligence2012Inngår i: Artificial General Intelligence: 5th International Conference, AGI 2012, Oxford, UK, December 8-11, 2012.

    Abstract [en]

    We argue that emotions play a central role in human cognition. It is therefore of interest to researchers with an aim to create artificial systems with human-level intelligence (or indeed beyond) to consider the functions of emotions in the human cognition whose complexity they aim to recreate. To this end, we review here several functional roles of emotions in human cognition at different levels, for instance in behavioural regulation and reinforcement learning. We discuss some of the neuroscientific and bodily underpinnings of emotions and conclude with a discussion of possible approaches, including existing efforts, to endow artificial systems with mechanisms providing some of the functions of human emotions. © 2012 Springer-Verlag.

    Situation awareness in eco-driving2015Inngår i: Cognitive Methods in Situation Awareness and Decision Support (CogSIMA), 2015 IEEE International Inter-Disciplinary Conference on, IEEE conference proceedings, 2015, s. 125-131Konferansepaper (Fagfellevurdert)
    Abstract [en]

    An increasing number of vehicles provide feedbackon eco-driving; information whose purpose it is to increase fuel efficiency in driving. The development of this feedback is relatively novel and there are currently no standards or long-term insights into best design strategies (e.g. leading to a permanent improvement in driving style).

    In this paper, we discuss the unexplored relevance of situation awareness (SA) research for eco-driving feedback, highlighting in particular that eco-driving feedback has to be understood as intricately tied into SA. Specifically, we argue that, for the purpose of promoting eco-friendly driving behaviour, the relevant information needs to be part of a driver SA without interfering with safety-critical aspects. We show that this requires eco-feedback systems to possess, themselves, a SA of the traffic situation. This lends support to arguments that SA in a road traffic context is different from SA in the military or aviation domain and takes on a more distributed nature. We conclude by suggesting that head-up displays are a particularly promising interface technology with which to implement the suggestions provided here.

    Driver adherence to recommendations from support systems improves if the systems explain why they are given: A simulator study2018Inngår i: Transportation Research Part F: Traffic Psychology and Behaviour, ISSN 1369-8478, E-ISSN 1873-5517, Vol. 56, s. 420-435Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper presents a large-scale simulator study on driver adherence to recommendationsgiven by driver support systems, specifically eco-driving support and navigation support.123 participants took part in this study, and drove a vehicle simulator through a pre-defined environment for a duration of approximately 10 min. Depending on the experi-mental condition, participants were either given no eco-driving recommendations, or asystem whose provided support was either basic (recommendations were given in theform of an icon displayed in a manner that simulates a heads-up display) or informative(the system additionally displayed a line of text justifying its recommendations). A naviga-tion system that likewise provided either basic or informative support, depending on thecondition, was also provided.

    Effects are measured in terms of estimated simulated fuel savings as well as engine brak-ing/coasting behaviour and gear change efficiency. Results indicate improvements in allvariables. In particular, participants who had the support of an eco-driving system spenta significantly higher proportion of the time coasting. Participants also changed gears atlower engine RPM when using an eco-driving support system, and significantly more sowhen the system provided justifications. Overall, the results support the notion that pro-viding reasons why a support system puts forward a certain recommendation improvesadherence to it over mere presentation of the recommendation.

    Finally, results indicate that participants’ driving style was less eco-friendly if the navi-gation system provided justifications but the eco-system did not. This may be due to par-ticipants considering the two systems as one whole rather than separate entities withindividual merits. This has implications for how to design and evaluate a given driver sup-port system since its effectiveness may depend on the performance of other systems in thevehicle.

    The inception of simulation: a hypothesis for the role of dreams in young children2011Inngår i: Proceedings of the 33rd Annual Conference of the Cognitive Science Society / [ed] Carlson, L.. et al., Cognitive Science Society, Inc., 2011, s. 231-236Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In the present paper, we present an argument and an initial model connecting research into the functional role of dreams with simulation theories. Traditionally, although theories that describe the refinement of simulations exist, the origin of these simulations is not considered in detail. Similarly, research into the functional role of dreams tends to focus on adults, with less regard to the dreams of young children.

    Here, we suggest that a functional role of dreams in infants through to early childhood may be the inception of these simulations. We show that the proposed model can present a unified explanation for functions of both the phenomenological experience of dreaming as well as other aspects of brain activity during sleeping, e.g. the processing of memories. Additionally, it explicitly provides an account for the development of simulations in early childhood, hypothesising that an initial function of dreams is the inception and development of simulations.

    Modeling the Development of Goal-Specificity in Mirror Neurons2011Inngår i: Cognitive Computation, ISSN 1866-9956, E-ISSN 1866-9964, Vol. 3, nr 4, s. 525-538Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Neurophysiological studies have shown that parietal mirror neurons encode not only actions but also the goal of these actions. Although some mirror neurons will fire whenever a certain action is perceived (goal-independently), most will only fire if the motion is perceived as part of an action with a specific goal. This result is important for the action-understanding hypothesis as it provides a potential neurological basis for such a cognitive ability. It is also relevant for the design of artificial cognitive systems, in particular robotic systems that rely on computational models of the mirror system in their interaction with other agents. Yet, to date, no computational model has explicitly addressed the mechanisms that give rise to both goal-specific and goal-independent parietal mirror neurons. In the present paper, we present a computational model based on a self-organizing map, which receives artificial inputs representing information about both the observed or executed actions and the context in which they were executed. We show that the map develops a biologically plausible organization in which goal-specific mirror neurons emerge. We further show that the fundamental cause for both the appearance and the number of goal-specific neurons can be found in geometric relationships between the different inputs to the map. The results are important to the action-understanding hypothesis as they provide a mechanism for the emergence of goal-specific parietal mirror neurons and lead to a number of predictions: (1) Learning of new goals may mostly reassign existing goal-specific neurons rather than recruit new ones; (2) input differences between executed and observed actions can explain observed corresponding differences in the number of goal-specific neurons; and (3) the percentage of goal-specific neurons may differ between motion primitives.

    How to Design Emergent Models of Cognition for Application-Driven Artificial Agents2016Inngår i: Neurocomputational Models of Cognitive Development and Processing: Proceedings of the 14th Neural Computation and Psychology Workshop / [ed] Katherine Twomey, Gert Westermann, Padraic Monaghan & Alastair Smith, Singapore: World Scientific, 2016, s. 115-129Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Emergent models of cognition are attractive for artificial cognitive agents because they overcome the brittleness of systems that are fully specified in axiomatic terms at design time, increasing, for example, the ability to deal with uncertainty and unforeseen events. When the agent is created to fulfil specific requirements defined by a given application, there is an apparent conflict between the emergent (i.e. self-defining) nature of the agent's behaviour and the pre-specified (i.e. axiomatically-defined) nature of the requirements.

    Here, we develop a framework for the design of emergent models of cognition whose behaviour can be shaped to fulfil application requirements while retaining the desired characteristics of emergence. We achieve this by viewing the artificial agent as forming an eco-system with the environment in which it is deployed. Consequently, the objective function that determines the agent's behaviour is cast in terms that factor in interaction with the environment (while not being controlled by it) and therefore implicitly includes the application requirements.

    This framework is particularly relevant to application driven research where artificial agents are designed to interact with humans in a certain manner. We illustrate this with the example of robot-enhanced therapy for children with autism spectrum disorder

    Abstract [en]

    Computational models of the mirror (neuron) system are attractive in robotics as they may inspire novel approaches to implemente.g. action understanding. Here, we present a simple self-organising map which forms the first part of larger ongoing work in building such amodel. We show that minor modifications to the standard implementation of such a map allows it to continuously learn new motor concepts.We find that this learning is facilitated by an initial motor babbling phase, which is in line with an embodied view of cognition. Interestingly,we also find that the map is capable of reproducing neurophysiologicaldata on goal-encoding mirror neurons. Overall, our model thus fulfils the crucial requirement of being able to learn new information throughout its lifetime. Further, although conceptually simple, its behaviour has interesting parallels to both cognitive and neuroscientific evidence.

    Distributed cognition at work - A systemic perspective on human based manufacturing2015Inngår i: Proceedings of ICMR 2015 / [ed] Linda Newnes, Aydin Nassehi & Vimal Dhokia, Bath, UK: University of Bath , 2015, s. 195-200Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Cognitive science is becoming increasingly central within human factors & ergonomics and, since at the same time, there has long been a call for a more systemic perspective in the area with a somewhat wider unit of analysis, this paper argues that the theoretical framework of distributed cognition would greatly benefit the area. It would offer a more complete understanding of the user within a greater context, be it social, cultural or materialistic. This paper aims to characterize and analyse the domain of manufacturing as a complex socio-technical system from a distributed cognition perspective; focusing on the use, mediation and integration of different forms of representations, tools and artefacts in this domain.  The paper further proposes and exemplifies benefits of using a distributed cognition framework in the manufacturing domain as studied by human factors and ergonomics.

    Initial development of a cognitive load assessment tool2014Inngår i: Advances in Cognitive Engineering and Neuroergonomics / [ed] Kay Stanney & Kelly S. Hale, AHFE , 2014, s. 223-232Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Interest in cognitive or mental workload has over the last couple of years increased drastically from a manufacturing application perspective.  More and more, people are becoming aware of the cognitive limitations that may have great impact on production outcome. The more easily observable area of physical ergonomics has been successfully investigated for a long time and it would seem as though focus has broadened to also include cognitive ergonomics. Considering the effects that a large cognitive load has on human performance, knowledge regarding the role of the cognizing human in a manufacturing environment could potentially have significant effect on production outcome (i.e. quality and productivity). With this in mind, developing and using methods and tools for assessment of the cognitive burden associated with particular tasks or workstations should be and is of substantial interest to the manufacturing industry. Whatever assessment methods exist in the scientific literature today are almost exclusively expert tools where significant expertise in the area of cognitive ergonomics/psychology/science is required. This paper reports parts of the development process and initial version of a non-expert tool for assessment of cognitive load in manual production environments, primarily manual assembly.

    Abstract [en]

    The increasing complexity and demands of assembly operations in manufacturing has been shown to lead to increased cognitive load in assembly workers. Previous work has outlined the complexity of an assembly worker's situation both in terms of difficulty and speed of work and there have been a few attempts at creating frameworks and methods for understanding the key aspects of what creates increased cognitive load. This paper presents the development of an analytic method, denoted CLAM (Cognitive Load Assessment for Manufacturing), and a tool for assessing cognitive load in manufacturing, primarily assembly. It outlines the journey of the development as well as discusses and problematizes relevant meta-methodological issues paired with method development. The intended contribution of the work is to make a difference in reducing the cognitive load of assembly workers on the shop floor, thus focusing the development on applicability and usability of the tool in practice. With this purpose in mind, focus of the method development has been on the practitioners, i.e. the method should not require any expert knowledge to be applied. The CLAM method and accompanying documentation such as a handbook containing instructions towards using the method and interpreting the results, is available in an online tool.

    Abstract [en]

    This paper presents a discussion on the role of embodied interaction with a basis in social embodiment effects and how they can be viewed in light of manufacturing ergonomics. The social embodiment effects are four statements, grounded in empirical findings, which highlight the interplay of social stimuli, embodied responses, and cognitive processing. They suggest and base an argument for how embodiment is central to cognitive processing, how bodily states interact extensively with cognitive states, and ultimately how embodied interaction is ubiquitous in human cognition. The paper further presents a view on how human based manufacturing can be studied in light of this argument, exploring other areas where social embodiment has been further researched, with an aim to suggest examples of where social embodiment effects might be found in manufacturing ergonomics and form a basis for future investigations.

    Modified pluralistic walkthrough for method evaluation in manufacturing2015Inngår i: Procedia Manufacturing, ISSN 2351-9789, Vol. 3, s. 5139-5146Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper presents a mixed evaluation design including quantitative and qualitative datain order to validate the scope, validity, and reliability of a recently developed CLAM method and tool. A central part of the evaluation was the use of a modified pluralistic walkthroughthat was created to better suit the industrial domain. The evaluation of CLAM was performed in a demonstration factory focusing on manufacturing of street scooters and electric pedal cars. The modified walkthrough was conducted on the shop floor, during on-going assembly, which stresses the representativeness of a real-world setting of manufacturing. The modified pluralistic walkthrough functioned accurately as an evaluation method of CLAM and the exhaustive comments and data from the user representatives were very beneficial. The quantitative results show convicting evidence of CLAM’s utility for assessing cognitive load while the qualitative results indicate that some modifications have to be made in order to enhance the actual tool in order to avoid misinterpretations resulting in misleading outcomes.

    Localization from an Indie Game Production Perspective: Why, When and How?2018Inngår i: DiGRA '18 - Proceedings of the 2018 DiGRA International Conference: The Game is the Message, Digital Games Research Association (DiGRA) , 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper investigates the process of game localization from an indie development perspective. The global nature of the digitally distributed game industry gives opportunities for game studios of all sizes to develop and distribute games on a global market. This poses a challenge for small independent developers with limited resources in funding and personnel, seeking to get as wide spread of their game as possible. To reach the players in other regions of the world localization needs to be done, taking language and other regional differences in mind. In an AAA or big-budget game production, these questions are handled by separate entities focusing solely on the localization process – but how do small independent game developers handle this? Indie game developers in Sweden, China and India have been interviewed to investigate the research question of how do indie game developers handle localization in the development process. The results points to a widespread use of community- and fan translation, and that only basic localization is done i.e. culturalization aspects are not considered. The results also show that the reason for localizing can be both business decisions but also to spread a specific message using games.

    Missing: Understanding the Reception of a Serious Game by Analyzing App Store Data2018Inngår i: INTERNATIONAL JOURNAL OF SERIOUS GAMES, E-ISSN 2384-8766, Vol. 5, nr 4, s. 3-22Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The focus of this paper is the design and player reception of a serious game called Missing released on Google Play with the intention of spreading awareness of trafficking and its impact on individuals and society. The aim of the paper is to investigate how the game has been received by its players, focusing on its trafficking theme, by analyzing player metrics and app store data available from the Google Play digital distribution system. The paper presents results focusing on three main knowledge contributions: the identification and characterization of the tension between the designer’s intention with a game’s mechanics and how they help to convey the message of the game, the identification of the complexity of finding relevant reviews relating to the serious theme of the game and the identification and characterization of the tension between the star rating and the content of the reviews. One of the conclusions is that even a negative review can mirror a positive result in terms of fulfillment of the purpose.

    Global Influences on Regional Industries: Game development in Nordic countries, China and India2016Inngår i: Decoding the Academic-Industrial-Gameplay Complex: Digital Game Practice, Research and Study in China, Taiwan and Chinese-Speaking Regions, Digital Games Research Association (DiGRA) , 2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The game development industry has historically been strongly associated with a few particularly dominant actors, namely Japan and the US. As a result, video game development processes and game content that have originated from these actors are often used as a benchmark for what game development is and can be. Discussing the games industry from these perspectives can, however, gloss over important nuances that make other game development regions unique. With this in mind, this paper intends to discuss the ways in which different cultural and regional contexts are reflected in the structure of local game development industries and, to some extent, in produced game content. To inform this discussion, the authors use the foundation and growth of game development practices in three different regions: the Nordic region, India, and China. These three regions serve as specific exemplifying cases of how video game industries and praxis can take different shapes depending on what resources and components they have available. The paper concludes that all regional games industries and game development practices are heavily influenced by the precedent set by historically dominant actors. This results in game content and development practices that often mimics pre-established standards. But, over time, the conditions surrounding the formation of regional industries manifest themselves in more locally unique content and development processes.

    A Taxonomy of Game Engines and the Tools that Drive the Industry2019Inngår i: DiGRA '19 - Proceedings of the 2019 DiGRA International Conference: Game, Play and the Emerging Ludo-Mix / [ed] Akinori Nakamura, Digital Games Research Association (DiGRA) , 2019Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Game engines are a vital part of a game production pipeline, but there is a vagueness of definitions regarding the boundaries of components in a game engine and the rest of the production tools used in a game development pipeline. The aim of this paper is to nuance the use of the term game engine and to put it into the context of a game development pipeline. Based on data from the current state of game production, a proposed taxonomy for tools in game development is presented. A distinction is made between user facing tools and product facing tools. A defining characteristic of the production pipeline and game engines is their plasticity. One of the conclusions is that a “game engine” as a single entity containing the whole game production pipeline is not desirable due to the large number of competences and needs involved in a game development project.

    Abstract [en]

    Nowadays, social media, ICT, mobile technologies and applications are increasingly used as tools for communication, interaction, building up social skills and unique learning environments. One of the latest trends observed in education is an attempt to streamline the learning process by applying educational digital games. Despite numerous research data, that confirms the positive effects of digital games, their integration into formal educational contexts is still relatively low. The purpose of this article is to analyze, discuss and conclude what is necessary to start using games as an instructional tool in formal education. In order to achieve this aim, a complex of qualitative research methods, including semi-structured expert interviews was applied. As the result, the potential of educational digital games to give a unique and safe learning environment with a wide spectrum of build-in assistive features, be efficient in specific training contexts, help memorize studied material and incorporate different learning styles, as well as to be individually adaptable, was determined. At the same time, the need for complex approach affecting the administration, IT departments, educators, students, parents, a strong skill set and a wide spectrum of different roles and tasks a teacher carries out in a digital game-based learning class were outlined. In conclusion and as a vector for further research, the organization of Education Design Laboratory as an integral part of a contemporary educational institution was proposed.

    On the Analysis of Utility and Risk for Masked Data in Big Data: A Small Data Analysis2018Inngår i: Frontiers in Artificial Intelligence and Applications: Artificial Intelligence Research and Development / [ed] Zoe Falomir, Karina Gibert, Enric Plaza, IOS Press , 2018, Vol. 308, s. 200-209Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Data privacy studies methods to ensure that disclosure of sensitive information does not take place. Masking methods are applied to databases prior to their release so that intruders cannot access sensitive information. Masking methods modify the data reducing its quality. Information loss measures have been defined to evaluate in what extent data is still useful for particular analysis. In the case of big data, masking data and evaluating its utility is a complex problem. In this paper we focus on information loss measurement and we explore if we can estimate or give bounds of information loss for large data sets using only random subsets of the whole data set.

    Some properties of Choquet integral based probability functions2015Inngår i: Acta et Commentationes Universitatis Tartuensis de Mathematica, ISSN 1406-2283, E-ISSN 2228-4699, Vol. 19, nr 1, s. 35-47Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Choquet integral permits us to integrate a function with respect to a non-additive measure. When the measure is additive it corresponds to the Lebesgue integral. This integral was used recently to define families of probability-density functions. They are the exponential family of Choquet integral (CI) based class-conditional probability-density functions, and the exponential family of Choquet– Mahalanobis integral (CMI) based class-conditional probability-density functions. The latter being a generalization of the former, and also a generalization of the normal distribution.

    In this paper we study some properties of these distributions, and study the application of a few normality tests.

    Transparency and Disclosure Risk in Data Privacy2015Inngår i: Proceedings of the Workshops of the EDBT/ICDT 2015 Joint Conference (EDBT/ICDT) / [ed] Peter M. Fischer, Gustavo Alonso, Marcelo Arenas, Floris Geerts, 2015, s. 246-Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    k-Anonymity and differential privacy can be considered examples of Boolean definitions of disclosure risk. In contrast, record linkage and uniqueness are examples of quantitative measures of risk. Record linkage is a powerful approach because it can model different types of scenarios in which an adversary attacks a protected database with some information and background knowledge. Transparency holds in data privacy when data is published together with details on their processing. This includes the data protection method used and its parameters. Intruders can use this information to improve their attacks. Specific record linkage algorithms can be defined to take into account this information, and to define more accurate disclosure risk measures. Machine learning and optimization techniques also permits us to increase the  effectiveness of record linkage algorithms. This talk will be focused on disclosure risk measures based on record linkage. We will describe how we can improve the performance of the algorithms under the transparency principle, as well as using machine learning and optimization techniques.

    Transparency and microaggregation2015Inngår i: UNECE SDC 2015, 2015Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Transparency has an important effect on disclosure risk. In general, masking methods have to be evaluated taking into account that intruders can use all available information to attack the data. When the masking method as well as their parameters are disclosed, this information can also be used by an intruder. In this talk we will review results on the effects of transparency in disclosure risk assessment for microdata giving special emphasis to microaggregation.
