  1. 16. Self-supervised Representation Learning for Visual Domains Beyond Natural Scenes

    Författare :Prakash Chandra Chhipa; Marcus Liwicki; Seiichi Uchida; Rajkumar Saini; Josep Lladós; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; self-supervised learning; representation learning; computer vision; learning with few labels; Maskininlärning; Machine Learning;

    Sammanfattning : This thesis investigates the possibility of efficiently adapting self-supervised representation learning on visual domains beyond natural scenes, e.g., medical imagining and non-RGB sensory images. LÄS MER

  3. 17. Data-Driven Techniques for Fluid Mechanics and Heat Transfer

    Författare :Jerol Soibam; Rebei Bel Fdhila; Konstantinos Kyprianidis; Ioanna Aslanidou; Ricardo Vinuesa Motilva; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Heat Transfer; Machine Learning; Deep Learning; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : One of the main challenges in fluid mechanics and heat transfer is the need for detailed studies andfast computational speed to monitor and optimise a system. These fluid/heat flows comprise time-dependent velocity, multi-scale, pressure, and energy fluctuations. LÄS MER

  4. 18. Towards Better Representation Learning in the Absence of Sufficient Supervision

    Författare :Arman Rahbar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Online learning; Neural network; Decision tree; Representation learning; Kernel embedding; Supervision; Knowledge transfer; Feature acquisition;

    Sammanfattning : We focus on the problem of learning representations from data in the situation where we do not have access to sufficient supervision such as labels or feature values. This situation can be present in many real-world machine learning tasks. We approach this problem from different perspectives summarized as follows. LÄS MER

  5. 19. Imaging imagining actions

    Författare :CJ Olsson; Lars Nyberg; A.Mark Williams; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mental training; motor training; novices; imaging; athletes; fMRI; internal imagery; motor representation; brain systems; practice; learning; transfer; active; Physiology; Fysiologi;

    Sammanfattning : Mental training has been studied extensively for the past century but we are still not completely sure how it affects brain and behavior. The aim of this doctoral thesis was to examine one aspect of mental training i.e. motor imagery. LÄS MER

  7. 20. Snakes and Ladders : Developmental Aspects of Lexical-Conceptual Relationships in the Multilingual Mental Lexicon

    Författare :Lari-Valtteri Suhonen; Språkinlärning; []
    Nyckelord :HUMANIORA; HUMANITIES; third language acquisition; cross-linguistic influence; mental lexicon; multilingualism; psychotypology; L3; attrition; second language acquisition; SLA; TLA; transfer; concept; cognitive control; working memory; CLI; multidirectional; multilingual mental lexicon; MML; acquisition; learning; translation ambiguity; introspection; longitudinal;

    Sammanfattning : One phenomenon causing issues for language learners in the form of cross-linguistic influence (CLI) is translation ambiguity (Eddington & Tokowicz, 2013). Translation ambiguity refers to a situation where word meanings are different in a speaker’s languages. LÄS MER
