  2. 1. Understanding Neural Machine Translation : An investigation into linguistic phenomena and attention mechanisms

    Author : Gongbo Tang; Joakim Nivre; Rico Sennrich; Philipp Koehn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neural machine translation; Linguistic phenomena; Ambiguity; Long-range dependency; Morphology; Negation; Attention mechanisms; Interpretation; Computational Linguistics; Datorlingvistik;

    Abstract : In this thesis, I explore neural machine translation (NMT) models via targeted investigation of various linguistic phenomena and thorough exploration of the internal structure of NMT models, in particular the attention mechanism. With respect to linguistic phenomena, I explore the ability of NMT models to translate ambiguous words, to learn long-range dependencies, to learn morphology, and to translate negation—linguistic phenomena that have been challenging for the older paradigm of statistical machine translation.

  4. 2. Mechanisms behind Cadmium-Induced Teratogenicity

    Author : Estíbaliz López Fernández de Villaverde; Lennart Dencker; Ulf Eriksson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; Cadmium; Teratogenesis; Exencephaly; Mechanisms; Toxikologi; Toxicology; Toxikologi;

    Abstract : Heavy metals polluting our environment cause concern for developing organisms. Among them, cadmium with extremely slow elimination from the body, causes lower birth weight in humans but has not been classify as a human teratogen. Studies in different laboratory animals have shown that cadmium indeed is a potent teratogen. READ MORE

  5. 3. Neural circuitry mechanisms in decision-making

    Author : Xinming Wang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The brain is the exclusive organ that makes decisions for humans and the society. In this thesis, I will discuss recent advances in the understanding of neuroscientific mechanisms in decision-making. Decision-making is not a new topic in the human history, but it has existed for thousands of years. READ MORE

  7. 5. How the past becomes present : neural mechanisms governing retrieval from episodic memory

    Author : Kristiina Kompus; Lars Nyberg; Katrine Åhlström Riklund; Emrah Düzel; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; episodic retrieval; cognitive control; retrieval intention; prefrontal cortex; functional magnetic resonance imaging; event-related potentials; Neurophysiology; Neurofysiologi; diagnostisk radiologi; Diagnostic Radiology;

    Abstract : Remembering previously experienced events can happen as a result of an effortful retrieval attempt. At other occasions, a memory can enter our minds without any apparent effort – or, indeed, intention - to retrieve. READ MORE
