  2. 1. Gaussian Bridges : Modeling and Inference

    Author : Maik Görgens; Ingemar Kaj; Svante Janson; Mikhail Lifshits; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical Statistics; Matematisk statistik;

    Abstract : This thesis consists of a summary and five papers, dealing with the modeling of Gaussian bridges and membranes and inference for the α-Brownian bridge.In Paper I we study continuous Gaussian processes conditioned that certain functionals of their sample paths vanish. We deduce anticipative and non-anticipative representations for them. READ MORE

  4. 2. Bayesian Inference for Nonlinear Dynamical Systems : Applications and Software Implementation

    Author : Jerker Nordh; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Indoor Navigation; pyParticleEst; Software Implementation; Simultaneous Localization and Mapping; Parameter Estimation; System Identification; Sequential Importance Sampling; Particle Filter; Bayesian Inference; Markov Chain Monte Carlo; Particle Smoother;

    Abstract : The topic of this thesis is estimation of nonlinear dynamical systems, focusing on the use of methods such as particle filtering and smoothing. There are three areas of contributions: software implementation, applications of nonlinear estimation and some theoretical extensions to existing algorithms. READ MORE

  5. 3. Selection of smoothing parameters with application in causal inference

    Author : Jenny Häggström; Xavier de Luna; Marie Wiberg; Yanyuan Ma; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Smoothing parameter selection; Nonparametric regression; Semiparametric additive model; Double smoothing; Causal inference; BMI; Divorce; Statistics; Statistik; Statistics; statistik;

    Abstract : This thesis is a contribution to the research area concerned with selection of smoothing parameters in the framework of nonparametric and semiparametric regression. Selection of smoothing parameters is one of the most important issues in this framework and the choice can heavily influence subsequent results. READ MORE

  6. 4. Robust inference of gene regulatory networks : System properties, variable selection, subnetworks, and design of experiments

    Author : Torbjörn E. M. Nordling; Elling W Jacobsen; Rolf Findeisen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; network inference; reverse engineering; variable selection; model selection; feature selection; subset selection; system identification; system theory; network theory; subnetworks; design of experiments; perturbation experiments; gene regulatory networks; biological networks;

    Abstract : In this thesis, inference of biological networks from in vivo data generated by perturbation experiments is considered, i.e. deduction of causal interactions that exist among the observed variables. Knowledge of such regulatory influences is essential in biology. READ MORE

  7. 5. Protein Mixture Inference as Hitting Set Variants and Linear Algebra Problems

    Author : Leonid Molokov; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Union Editing; Shotgun proteomics; Parameterized complexity; Protein Inference; Shared Peptides; Set Cover; Hypergraph; Hitting Set; Fixed Parameter Tractable; Protein Quan- ti; Star Editing;

    Abstract : This work is dedicated to the problems of protein inference and quantification in bottom-up proteomics, and, in particular, in shotgun proteomics. We adopt a rather classical approach of representing inference problem as a set cover, where proteins are understood as sets of their observations: peptides' masses or sequences. READ MORE
