  1. 16. Analytical Approximations for Bayesian Inference

    Författare :Tohid Ardeshiri; Fredrik Gustafsson; Johan Wolfgang Koch; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Bayesian inference is a statistical inference technique in which Bayes’ theorem is used to update the probability distribution of a random variable using observations. Except for few simple cases, expression of such probability distributions using compact analytical expressions is infeasible. LÄS MER

  2. 17. From genomes to post-processing of Bayesian inference of phylogeny

    Författare :Raja Hashim Ali; Lars Arvestad; Dannie Durand; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bayesian inference; Computer Science; Datalogi;

    Sammanfattning : Life is extremely complex and amazingly diverse; it has taken billions of years of evolution to attain the level of complexity we observe in nature now and ranges from single-celled prokaryotes to multi-cellular human beings. With availability of molecular sequence data, algorithms inferring homology and gene families have emerged and similarity in gene content between two genes has been the major signal utilized for homology inference.

  3. 18. Bayesian Inference in Terrain Navigation

    Författare :Niclas Bergman; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Terrain navigation is a concept for autonomous aircraft navigation. If measurements of the terrain height over mean sea-level are collected along the aircraft flight path, an estimate of the aircraft position can be formed by matching these measurements with a digital reference terrain map. This matching is a recursive nonlinear estimation problem. LÄS MER

  4. 19. Bayesian Modeling of Conditional Densities

    Författare :Feng Li; Mattias Villani; Sylvia Frühwirth-Schnatter; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bayesian inference; Density estimation; smooth mixtures; surface regression; copulas; Markov chain Monte Carlo; Statistics; statistik;

    Sammanfattning : This thesis develops models and associated Bayesian inference methods for flexible univariate and multivariate conditional density estimation. The models are flexible in the sense that they can capture widely differing shapes of the data. The estimation methods are specifically designed to achieve flexibility while still avoiding overfitting. LÄS MER

  5. 20. Babblers, Biogeography and Bayesian Reasoning

    Författare :Magnus Gelang; Per Ericson; Per Alström; Isabel Sanmartín Bastida; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Africa; Asia; Bayesian inference; biogeography; Cettidae; dispersal; extinction; Middle East; persistence; Sylvioidea; Sylviidae; Timaliidae; vicariance; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : In this thesis, I try to proceed one step further towards an understanding of the biogeographic processes forming the distribution patterns of organisms that we see today. Babblers and warblers are diverse groups of passerines that are phylogenetically intermixed with other groups in the superfamily Sylvioidea. LÄS MER
