  1. 1. Geometric Models of Similarity

    Författare :Mikael Johannesson; Kognitionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; symmetry; similarity; separable dimensions; prominence; multidimensional scaling; Minkowski metric; machine learning; integral dimensions; familiarity; geometric models; distance metric; asymmetry; conceptual spaces; Computer science; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll; Geometry; algebraic topology; Geometri; algebraisk topologi;

    Sammanfattning : This dissertation examines and discusses some phenomena related to the geometric representation of similarity. It takes its inspiration from the existing body of empirical research within the fields of perceptual and cognitive psychology, but also connects to certain areas of machine learning. LÄS MER

  3. 2. Deep Perceptual Loss and Similarity

    Författare :Gustav Grund Pihlgren; Marcus Liwicki; Fredrik Sandin; Hugo Larochelle; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Image Similarity; Perceptual Similarity; Perceptual Loss; Deep Features; Deep Learning; Machine Learning; Maskininlärning;

    Sammanfattning : This thesis investigates deep perceptual loss and (deep perceptual) similarity; methods for computing loss and similarity for images as the distance between the deep features extracted from neural networks. The primary contributions of the thesis consist of (i) aggregating much of the existing research on deep perceptual loss and similarity, and (ii) presenting novel research into understanding and improving the methods.

  4. 3. Reasoning by Analogy - A Study on Analogy-Based Arguments in Law

    Författare :David Reidhav; Juridiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Reasoning by analogy; legal argumentation; legal methodology; formal justice; stare decisis; precedent; analogy; proportional analogy; similarity; dimensional property; comparative similarity; arguments from analogy; closure rule; jurisprudence; allmän rättslära;

    Sammanfattning : This doctoral dissertation is a study on analogy-based arguments in law. Its overarching aim is to clarify reasoning by analogy in law. A model is proposed for analyzing and assessing arguments from analogy in law. LÄS MER

  5. 4. Similarity-based processes in human multiple-cue judgment : evidence from brain imaging and cognitive modelling

    Författare :Sara Stillesjö; Linnea Karlsson Wirebring; Lars Nyberg; Håkan Nilsson; Alan Sanfey; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multiple-cue judgment; similarity-based; rule-based; exemplar-based model; fMRI; cognitive modelling;

    Sammanfattning : Background: We often make judgments that require the consideration of several sources of information. For example, a teacher that grades a student´s exam question often integrates multiple sources of information (cues: details provided in the answer) into a single criterion dimension (the grade).

  7. 5. Essays in Public Finance and Behavioral Economics

    Författare :Arnaldur Stefánsson; Per Engström; Eva Mörk; Mats Persson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Frisch elasticity of labor supply; identification; elasticity heterogeneity; tax compliance; loss aversion; prospect theory; benefit take-up; similarity; distributive justice; moral decision-making; ambiguity attitudes; framing; consistency of choice; Economics; Nationalekonomi;

    Sammanfattning : Essay I: I study how individuals adjust their labor supply in response to a year with tax free income. Due to a transformation from a retroactive to a pay-as-you-earn tax system, income earned on the Icelandic labor market in 1987 was never taxed. LÄS MER
