  2. 1. Bounded Rationality and Exemplar Models

    Author : Magnus Persson; Peter Juslin; Nick Chater; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; PROBEX; Lazy Algorithm; Probabilistic Inference; Decision Making; Bounded Rationality; Ecological Rationality; Take The Best; exemplar models; correspondence; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Bounded rationality is the study of how human cognition with limited capacity is adapted to handle the complex information structures in the environment. This thesis argues that in order to understand the bounded rationality of decision processes, it is necessary to develop decision theories that are computational process models based upon basic cognitive and perceptual mechanisms.

  4. 2. Visual Representations and Models: From Latent SVM to Deep Learning

    Author : Hossein Azizpour; Stefan Carlsson; Barbara Caputo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Vision; Machine Learning; Artificial Intelligence; Deep Learning; Learning Representation; Deformable Part Models; Discriminative Latent Variable Models; Convolutional Networks; Object Recognition; Object Detection; Computer Science; Datalogi;

    Abstract : Two important components of a visual recognition system are representation and model. Both involves the selection and learning of the features that are indicative for recognition and discarding those features that are uninformative. READ MORE

  5. 3. Factors Shaping Process and Representation in Multiple-Cue Judgment

    Author : Anna-Carin Olsson; Peter Juslin; Nigel Harvey; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Multiple-Cue Judgment; categorization; cognitive processes; knowl-edge representations; exemplar-based models; cue abstraction models; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : This thesis investigates the cognitive processes and representations underlying human judgment in a multiple-cue judgment task. Several recent models as-sume that people have several qualitatively distinct and competing levels of knowledge representations (Ashby, Alfonso-Reese, Turken, & Waldron, 1998; Erickson & Kruschke, 1998; Nosofsky, Palmeri, & McKinley, 1994; Sloman, 1996).

  6. 4. A Division-of-Labor Hypothesis : Adaptations to Task Structure in Multiple-Cue Judgment

    Author : Linnea Karlsson; Peter Juslin; David Lagnado; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiple-cue judgment; exemplar models; cue abstraction; cue-combination rule; Cognitive science; Kognitionsvetenskap;

    Abstract : Judgments that demand consideration of pieces of information in the environment occur repeatedly throughout our lives. One professional example is that of a physician that considers multiple symptoms to make a judgment about a patient’s disease. READ MORE

  7. 5. Modelling Allelic and DNA Copy Number Variations using Continuous-index Hidden Markov Models

    Author : Susann Stjernqvist; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hidden Markov models; DNA copy number; allelic copy number; Markov chain Monte Carlo;

    Abstract : In human cells there are usually two copies of each chromosome, but in cancer cells abnormalities could exist. The differences consist of segments of chromosomes with an altered number of copies. There can be deletions as well as amplifications and the lengths of the segments can also vary. READ MORE
