  1. 1. Learning of probabilistic inference tasks : effects of uncertainty and function form

    Författare :Håkan Alm; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inference; learning; cognition;

    Sammanfattning : This thesis is concerned with the problem of how people learn to use uncer­tain information for making judgments. The general framework for the thesis is Social Judgment Theory (SJT). First the S3T paradigm, and some research conducted within the paradigm, is briefly described, and a series of four empirical studies is summarized. LÄS MER

  3. 2. Bayesian Phylogenetic Inference : Estimating Diversification Rates from Reconstructed Phylogenies

    Författare :Sebastian Höhna; Tom Britton; Fredrik Ronquist; Ziheng Yang; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Phylogenetics; Bayesian inference; Graphical Models; Birth-Death Process; Diversification; matematisk statistik; Mathematical Statistics;

    Sammanfattning : Phylogenetics is the study of the evolutionary relationship between species. Inference of phylogeny relies heavily on statistical models that have been extended and refined tremendously over the past years into very complex hierarchical models. LÄS MER

  4. 3. Bayesian inference in probabilistic graphical models

    Författare :Felix Leopoldo Rios; Tatjana Pavlenko; Alun Thomas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphical models; Bayesian inference; predictive classification; decomposable graphs; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Sammanfattning : This thesis consists of four papers studying structure learning and Bayesian inference in probabilistic graphical models for both undirected and directed acyclic graphs (DAGs).Paper A presents a novel algorithm, called the Christmas tree algorithm (CTA), that incrementally construct junction trees for decomposable graphs by adding one node at a time to the underlying graph.

  5. 4. Perspectives on Probabilistic Graphical Models

    Författare :Dong Liu; Ragnar Thobaben; Harri Lähdesmäki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bayesian methods; graphical models; inference; learning; statistics; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Probabilistic graphical models provide a natural framework for the representation of complex systems and offer straightforward abstraction for the interactions within the systems. Reasoning with help of probabilistic graphical models allows us to answer inference queries with uncertainty following the framework of probability theory. LÄS MER
