  2. 1. Action in Mind : A Neural Network Approach to Action Recognition and Segmentation

    Author : Zahra Gharaee; Kognitiv modellering; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Action recognition; motion perception; cognitive robotics; hierarchical models; self-organizing neural networks; growing grids; attention;

    Abstract : Recognizing and categorizing human actions is an important task with applications in various fields such as human-robot interaction, video analysis, surveillance, video retrieval, health care system and entertainment industry.This thesis presents a novel computational approach for human action recognition through different implementations of multi-layer architectures based on artificial neural networks.

  4. 2. Material perception and action : The role of material properties in object handling

    Author : Kristin Ingvarsdottir; Kognitiv modellering; []
    Keywords : HUMANIORA; HUMANITIES; material perception; visual properties; motor planning; cognition; humanoid robot;

    Abstract : This dissertation is about visual perception of material properties and their role in preparation for object handling. Usually before an object is touched or picked-up we estimate its size and shape based on visual features to plan the grip size of our hand. READ MORE

  5. 3. Contours of Cognition

    Author : Trond A. Tjøstheim; Kognitiv modellering; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; computational; cognitive; neuroscience; perception; memory; spatial cognition; trust; pupil dynamics; reflection; thinking; intelligence; reinforcement learning; foraging; allostasis; decision making;

    Abstract : This thesis concerns the nature of cognition. It posits that cognitive processes primarily are means to maintain allostasis in organisms whose ecological niches require movement to approach food-resources and avoid predation. READ MORE

  6. 4. Analogical reasoning in science education : - connections to semantics and scientific modelling in thermodynamics

    Author : Jesper Haglund; Helge Strömdahl; Konrad Schönborn; Roland Kjellander; Kevin Dunbar; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; science education; thermodynamics; analogical reasoning; semantics; scientific modelling; naturvetenskapsdidaktik; termodynamik; analogiskt tänkande; semantik; vetenskaplig modellering;

    Abstract : Analogiskt tänkande är en central kognitiv förmåga som vi använder i vardagslivet, såväl som i mer formella sammanhang, såsom i forskning och undervisning. Föreliggande avhandling behandlar hur analogier och analogiskt tänkande, uppmärksamhet på semantik och förståelse för vetenskaplig modellering kan användas för att hantera utmaningar i naturvetenskapsundervisningen, särskilt inom området termodynamik.

  7. 5. Lexical and Acoustic Modelling of Swedish Prosody

    Author : Johan Frid; Fonetik; []
    Keywords : HUMANIORA; HUMANITIES; phonology; Phonetics; stress; dialects; Swedish; word accents; letter-to-sound; text-to-speech; modelling; intonation; prosody; speech technology; Fonetik; fonologi; Scandinavian languages and literature; Nordiska språk språk och litteratur ;

    Abstract : Prosody and intonation are very important ingredients of human speech. In speech technology, text-to-speech (TTS) and automatic speech recognition (ASR) systems must incorporate prosodic models in order to reach acceptable performances. READ MORE
