  2. 1. Estimation of the reliability of systems described by the Daniels Load-Sharing Model

    Author : Patrik Rydén; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-parametric and parametric estimation; Equal Load-sharing models; asymptotic distribution; martingale; resam-pling; life testing; reliability; Mathematical statistics; Matematisk statistik;

    Abstract : We consider the problem of estimating the failure stresses of bundles (i.e. the tensile forces that destroy the bundles), constructed of several statisti-cally similar fibres, given a particular kind of censored data. READ MORE

  4. 2. Learning Stochastic Nonlinear Dynamical Systems Using Non-stationary Linear Predictors

    Author : Mohamed Abdalmoaty; Håkan Hjalmarsson; Jimmy Olsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Stochastic Nonlinear Systems; Nonlinear System Identification; Learning Dynamical Models; Maximum Likelihood; Estimation; Process Disturbance; Prediction Error Method; Non-stationary Linear Predictors; Intractable Likelihood; Latent Variable Models; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The estimation problem of stochastic nonlinear parametric models is recognized to be very challenging due to the intractability of the likelihood function. Recently, several methods have been developed to approximate the maximum likelihood estimator and the optimal mean-square error predictor using Monte Carlo methods. READ MORE

  5. 3. Quantization of Random Processes and Related Statistical Problems

    Author : Mykola Shykula; Oleg Seleznjev; Patrik Rydén; Igor Rychlik; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; scalar quantization; random process; rate; distortion; additive noise model; run-length encoding; compression; sample estimate; asymptotical normality; Mathematical statistics; Matematisk statistik;

    Abstract : In this thesis we study a scalar uniform and non-uniform quantization of random processes (or signals) in average case setting. Quantization (or discretization) of a signal is a standard task in all nalog/digital devices (e.g., digital recorders, remote sensors etc. READ MORE

  6. 4. Statistical analysis and simulation methods related to load-sharing models

    Author : Patrik Rydén; Yuri Belyaev; Uwe Jensen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-parametric and parametric estimation; load-sharing models; asymptotic distribution; martingale; resampling; life testing; reliability;

    Abstract : We consider the problem of estimating the reliability of bundles constructed of several fibres, given a particular kind of censored data. The bundles consist of several fibres which have their own independent identically dis-tributed failure stresses (i.e.the forces that destroy the fibres). READ MORE

  7. 5. Machine learning with state-space models, Gaussian processes and Monte Carlo methods

    Author : Andreas Svensson; Thomas B. Schön; Fredrik Lindsten; Carl Edward Rasmussen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Machine learning; State-space models; Gaussian processes; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Numbers are present everywhere, and when they are collected and recorded we refer to them as data. Machine learning is the science of learning mathematical models from data. Such models, once learned from data, can be used to draw conclusions, understand behavior, predict future evolution, and make decisions. READ MORE
