1. 1. Studies in knowledge representation : modeling change - the frame problem : pictures and words

   Författare :Lars-Erik Janlert; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analogical; artificial intelligence; digital; exemplification; frame problem; Goodman; knowledge representation; metaphysics; model; pictorial representation; symbol theory;

   Sammanfattning : In two studies, the author attempts to develop a general symbol theoretical approach to knowledge representation.The first study, Modeling change -the frame problem, critically examines the - so far unsuccessful - attempts to solve the notorious frame problem. LÄS MER

3. 2. Cognition Rehearsed : Recognition and Reproduction of Demonstrated Behavior

   Författare :Erik Billing; Thomas Hellström; Lars Erik Janlert; Danica Kragic; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Behavior Recognition; Learning and Adaptive Systems; Learning from Demonstration; Neurocomputational Modeling; Robot Learning; computer and systems sciences; data- och systemvetenskap;

   Sammanfattning : The work presented in this dissertation investigates techniques for robot Learning from Demonstration (LFD). LFD is a well established approach where the robot is to learn from a set of demonstrations. The dissertation focuses on LFD where a human teacher demonstrates a behavior by controlling the robot via teleoperation. LÄS MER

4. 3. Cognition reversed : Robot learning from demonstration

   Författare :Erik Billing; Lars Erik Janlert; Thomas Hellström; Tom Ziemke; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Cognitive science; Kognitionsvetenskap; computer and systems sciences; data- och systemvetenskap;

   Sammanfattning : The work presented in this thesis investigates techniques for learning from demonstration (LFD). LFD is a well established approach to robot learning, where a teacher demonstrates a behavior to a robot pupil. This thesis focuses on LFD where a human teacher demonstrates a behavior by controlling the robot via teleoperation. LÄS MER

5. 4. Cognitive Interactive Robot Learning

   Författare :Benjamin Fonooni; Hellström Thomas; Lars Erik Janlert; Christian Balkenius; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Learning from Demonstration; Imitation Learning; Human Robot Interaction; High-Level Behavior Learning; Shared Control; Cognitive Architectures; Cognitive Robotics; Priming; business data processing; administrativ databehandling;

   Sammanfattning : Building general purpose autonomous robots that suit a wide range of user-specified applications, requires a leap from today's task-specific machines to more flexible and general ones. To achieve this goal, one should move from traditional preprogrammed robots to learning robots that easily can acquire new skills. LÄS MER

7. 5. From Conceptual Links to Causal Relations — Physical-Virtual Artefacts in Mixed-Reality Space

   Författare :Thomas Pederson; Lars-Erik Janlert; William Buxton; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Människa-dator-interaktion; Human-Computer Interaction; Mixed Reality; Augmented Reality; Ubiquitous Computing; Pervasive Computing; Graspable User Interfaces; Tangible User Interfaces; Wearable Computing; Context Awareness; User Modelling; Interaction Design; Systems Design; Människa-dator-interaktion; Information technology; Informationsteknologi; business data processing; administrativ databehandling;

   Sammanfattning : This thesis presents a set of concepts and a general design approach for designing Mixed Reality environments based on the idea that the physical (real) world and the virtual (digital) world are equally important and share many properties. Focus is on the design of a technology infrastructure intended to relieve people from some of the extra efforts currently needed when performing activities that make heavy use of both worlds. LÄS MER
