  2. 6. Nonparametric Statistical Inference for Entropy-type Functionals

    Author : David Källberg; Oleg Seleznjev; Timo Koski; Umeå universitet; []
    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

  4. 7. Perspectives on Probabilistic Graphical Models

    Author : Dong Liu; Ragnar Thobaben; Harri Lähdesmäki; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 8. Analytical Approximations for Bayesian Inference

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

    Abstract : 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. READ MORE

  6. 9. Bootstrap inference in time series econometrics

    Author : Mikael P. Gredenhoff; Handelshögskolan i Stockholm; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : This dissertation contains five essays in the field of time series econometrics. The main issue discussed is the lack of coherence between small sample and asymptotic inference. Frequently, in modern econometrics distributional results are strictly only valid for a hypothetical infinite sample. READ MORE

  7. 10. Bayesian Inference for Automotive Applications

    Author : Maryam Fatemi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Environment perception is an important aspect of modern automated systems. The perception consists of fusing information from different sensors to estimate variables which provide a description of the scene. READ MORE
