  1. 21. 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

  3. 22. Letters & Bytes : Sociotechnical Studies of Distance Education

    Författare :Francis Lee; Ulf Mellström; Boel Berner; Adrian Mackenzie; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sociology of technology; distance education; education; history of education; correspondence education; Learning Objects; standardization; actor-network theory; associations; translation; dispositif; tekniksociologi; distansutbildning; utbildning; korrespondensundervisning; lärobjekt; standardisering; aktörsnätverks teori; översättning; associering; dispositif; Technology and social change; Teknik och social förändring; Sociology; Sociologi; History of technology; Teknikhistoria; Education; Pedagogik; Informatics and systems science; Informatik och systemvetenskap;

    Sammanfattning : This dissertation studies the social aspects of technology in distance education trough the lens of history – in the form of correspondence education – and a possible future – in the form of a project of technical standardization, Learning Objects. The studied cases form a reflexive tool that allows the present of distance education to be seen in perspective. LÄS MER

  4. 23. Lärande genom möten : En studie av kommunikation mellan lärare och studerande i klassrumsmiljö och datorbaserad nätverksmiljö

    Författare :Eva Svärdemo Åberg; Staffan Selander; Shirley Booth; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; alterity; asynchronous; classroom; distance education; computer-based network environment; computer mediated communication; ICT; intersubjectivity; learning process; sociocultural theory; Education; Pedagogik;

    Sammanfattning : The aim of this dissertation is to study the social interaction of teachers and students, and their reflections on this interaction. This is done in order to illuminate opportunities and constraints of communication and learning in two different environments within distance education – in the classroom and in a computer-based network environment.

  5. 24. Proximity and Learning in Internationalisation : Small Swedish IT firms in India

    Författare :Kristina Westermark; Brita Hermelin; Charlotta Hedberg; Andrew Jones; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Internationalisation; proximity; learning; communities of practice; India; Sweden; ICT; service; IT; small firms; Human Geography; kulturgeografi;

    Sammanfattning : The four IT service firms of this thesis set out to interact and collaborate between their offices in Sweden and in India, some more intensely and frequently than others. In the process of their internationalisation, these small service firms find ways, or go through a process of learning how to collaborate in an international setting. LÄS MER

  7. 25. On Deep Machine Learning Based Techniques for Electric Power Systems

    Författare :Ebrahim Balouji; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deep Learning; Cable faults; phase locked loop; Flicker; Harmonics and Interharmonics; Reinforcement learning; Voltage Dip; Active Power filter; Machine Learning; Voltage fluctuation; Partial Discharges;

    Sammanfattning : This thesis provides deep machine learning-based solutions to real-time mitigation of power quality disturbances such as flicker, voltage dips, frequency deviations, harmonics, and interharmonics using active power filters (APF). In an APF the processing delays reduce the performance when the disturbance to be mitigated is tima varying. LÄS MER
