  1. 1. Studies in knowledge representation : modeling change - the frame problem : pictures and words

    Författare :Lars-Erik Janlert; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analogical; artificial intelligence; digital; exemplification; frame problem; Goodman; knowledge representation; metaphysics; model; pictorial representation; symbol theory;

    Sammanfattning : In two studies, the author attempts to develop a general symbol theoretical approach to knowledge representation.The first study, Modeling change -the frame problem, critically examines the - so far unsuccessful - attempts to solve the notorious frame problem. LÄS MER

  3. 2. Gender and representation : investigations of bias in natural language processing

    Författare :Hannah Devinney; Henrik Björklund; Jenny Björklund; Christian Hardmeier; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NLP; natural language processing; gender bias; social impact of AI; gendered pronouns; neopronouns; gender studies; topic modeling; Computer Science; datalogi; computational linguistics; datorlingvistik; genusvetenskap; gender studies;

    Sammanfattning : Natural Language Processing (NLP) technologies are a part of our every day realities. They come in forms we can easily see as ‘language technologies’ (auto-correct, translation services, search results) as well as those that fly under our radar (social media algorithms, 'suggested reading' recommendations on news sites, spam filters).

  4. 3. Grafisk och algebraisk representation : Gymnasieelevers förståelse av linjära funktioner

    Författare :Annika Pettersson; Igor Gachkov; Kerstin Pettersson; Lovisa Sumpter; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; linear function; graphic representation; scale; concept image; Matematik; Mathematics;

    Sammanfattning : This thesis concerns upper secondary students’ understanding of algebraic and graphic representation of linear functions. Components of the students’ concept images, so-called ‘concept elements’, were studied as a way to capture their understanding. LÄS MER

  5. 4. On the Clebsch-Gordan problem for quiver representations

    Författare :Martin Herschend; Ernst Dieterich; Alex Martsinkovsky; Karin Erdmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Algebra and geometry; quiver; quiver representation; tensor product; Clebsch-Gordan problem; representation ring; bialgebra; Galois covering; Algebra och geometri;

    Sammanfattning : On the category of representations of a given quiver we define a tensor product point-wise and arrow-wise. The corresponding Clebsch-Gordan problem of how the tensor product of indecomposable representations decomposes into a direct sum of indecomposable representations is the topic of this thesis.

  7. 5. Explaining everyday problem solving

    Författare :Annika Wallin; Kognitionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; domain-specificity; ecological rationality; evolutionary psychology; practice theory; situated action; universal problem solver; everyday cognition; Explanations; everyday problem solving; domain-generality; causality; social information; Psychology; Psykologi;

    Sammanfattning : How well can we explain natural occurrences of cognitive behaviours given the theoretical frameworks available to us today? The thesis explores what has to be assumed in cognitive theory in order to provide such an explanation, in contrast to being able to predict behaviour under controlled circumstances. The behaviours considered are all of the type described as involving higher level cognition or being representation hungry. LÄS MER
