  1. 1. Machine learning using approximate inference Variational and sequential Monte Carlo methods

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Christian Andersson Naesseth; Thomas Schön; Fredrik Lindsten; Iain Murray; [2018]

    Abstract : Automatic decision making and pattern recognition under uncertainty are difficult tasks that are ubiquitous in our everyday life. The systems we design, and technology we develop, requires us to coherently represent and work with uncertainty in data. READ MORE

  2. 2. Bayesian inference in probabilistic graphical models

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Felix Leopoldo Rios; Tatjana Pavlenko; Alun Thomas; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphical models; Bayesian inference; predictive classification; decomposable graphs; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : 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.

  3. 3. Exact inference in Bayesian networks and applications in forensic statistics

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Ivar Simonsson; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; familial relationship inference; Bayesian networks; exact inference; forensic statistics; variable elimination; mutation models;

    Abstract : Bayesian networks (BNs) are commonly used when describing and analyzing relationships between interacting variables. Approximate methods for performing calculations on BNs are widely used and well developed. READ MORE

  4. 4. Statistical inference with deep latent variable models

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Najmeh Abiri; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Deep Learning; Generative Models; Variational Inference; Missing data; Imputation; Fysicumarkivet A:2019:Abiri;

    Abstract : Finding a suitable way to represent information in a dataset is one of the fundamental problems in Artificial Intelligence. With limited labeled information, unsupervised learning algorithms help to discover useful representations. READ MORE

  5. 5. Nonparametric Statistical Inference for Entropy-type Functionals

    University dissertation from Umeå : Umeå universitet

    Author : David Källberg; Oleg Seleznjev; Timo Koski; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; entropy estimation; Rényi entropy; divergence estimation; quadratic density functional; U-statistics; consistency; asymptotic normality; Poisson convergence; stationary m-dependent sequence; inter-point distances; entropy maximizing distribution; two-sample problem; approximate matching; Mathematical Statistics; matematisk statistik;

    Abstract : In this thesis, we study statistical inference for entropy, divergence, and related functionals of one or two probability distributions. Asymptotic properties of particular nonparametric estimators of such functionals are investigated. We consider estimation from both independent and dependent observations. READ MORE
