1. 21. Representation and Learning for Robotic Grasping, Caging, and Planning

   Författare :Johannes Andreas Stork; Danica Kragic; Wolfram Burgard; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Grasping; Caging; Planning; State Representation; Optimization; Topology; Manipulation; Reinforcement Learning; Datalogi; Computer Science;

   Sammanfattning : Robots need to grasp, handle, and manipulate objects, navigate their environment, and understand the state of the world around them. Like all artificial intelligence agents, they have to make predictions, formulate goals, reason about actions, and make plans. LÄS MER

3. 22. Offline and Online Models for Learning Pairwise Relations in Data

   Författare :Fazeleh Sadat Hoseini; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mulit-Armed Bandit; Pairwise Relations; Performance Modeling; Motion Trajectory Clustering; Minimax Distance; Bottleneck Identification; Online Learning; Representation Learning; Memory Efficiency; Concurrent Programming; Thompson Sampling;

   Sammanfattning : Pairwise relations between data points are essential for numerous machine learning algorithms. Many representation learning methods consider pairwise relations to identify the latent features and patterns in the data. This thesis, investigates learning of pairwise relations from two different perspectives: offline learning and online learning. LÄS MER

4. 23. Tinget, rummet, besökaren : Om meningsskapande på museum

   Författare :Eva Insulander; Staffan Selander; Kerstin Smeds; Roger Säljö; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; didactic science; museums; exhibitions; learning; meaning-making; design; multimodality; representation; didaktik; museer; utställningar; lärande; meningsskapande; design; multimodalitet; representation; Didactics; didaktik; Education; Didactics;

   Sammanfattning : The main purpose of this thesis is to describe and analyse how museum visitors engage with and make meaning from what is being offered to them in terms of the various resources made available in two exhibitions. Yet another purpose is to describe and analyse the design of these exhibitions. LÄS MER

5. 24. Mathematical Learning Disability : Cognitive Conditions, Development and Predictions

   Författare :Rickard Östergren; Ulf Träff; Joakim Samuelsson; Örjan Dahlström; Åke Olofsson; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematical learning disability; dyscalculia; mathematical cognition; number sense; Matematiska inlärningssvårigheter; dyskalkyli; matematisk kognition; antalsuppfattning;

   Sammanfattning : The purpose of the present thesis was to test and contrast hypotheses about the cognitive conditions that support the development of mathematical learning disability (MLD). Following hypotheses were tested in the thesis: a) domain general deficit, the deficit is primarily located in the domain general systems such as the working memory, b) number sense deficit, the deficit is located in the innate approximate number system (ANS), c) numerosity coding deficit, the deficit is located to a exact number representation system, d) access deficit, the deficit is in the mapping between symbols and the innate number representational system (e.

7. 25. Making Possible by Making Visible : Learning through Visual Representations in Social Science

   Författare :Ann-Sofie Jägerskog; Cecilia Lundholm; Peter Davies; Magnus Hultén; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social science teaching; visual representation; pricing; causal relationships; teaching and learning; phenomenography; variation theory; practice theory; teaching-learning practice; epistemic practices; upper secondary school; design research; graphs; economics; social studies; ämnesdidaktik med inriktning mot de samhällsvetenskapliga ämnenas didaktik; Teaching and Learning with Specialisation in the Social Sciences Education;

   Sammanfattning : This thesis focuses upon the relationship between teaching and learning of dynamic phenomena and processes in social science and the use of visual representations in social science teaching. Teaching in social science uses many visual representations, such as models, flowcharts and diagrams, in order to help students to grasp phenomena, structures and processes in society. LÄS MER
