1. 1. Bayesian learning of structured dynamical systems

   Författare :Riccardo Sven Risuleo; Håkan Hjalmarsson; Johan Schoukens; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; bayesian learning; machine learning; Gaussian processes; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : In this thesis, we propose some Bayesian approaches to the identificationof structured dynamical systems. In particular, we consider block-orientedmodels in which a complex system is built starting from simple linear andnonlinear building blocks. LÄS MER

3. 2. 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

4. 3. Ultrasound prediction of large fetuses. Epidemiological and clinical investigations

   Författare :Gun Lindell; Lund Obstetrik och gynekologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Two-dimensional ultrasound; three-dimensional ultrasound; fetus; intrauterine growth; maternal characteristic; large-for-gestational age; antenatal calculation; Bayesian theorem; fetal weight; estimation; post-term fetus; fetal macrosomia;

   Sammanfattning : The proportions of newborns with a birth weight (BW) >4,000 g and of macrosomic newborns (BW >4,500 g) have increased during the last two decades, parallel with an increasing maternal pre-pregnancy body mass index (BMI) and age at the time for pregnancy. Delivery of a large fetus, especially >4,500 g might cause perinatal complications for both the mother and her child. LÄS MER

5. 4. Studies in plausibility theory, with applications to physics

   Författare :Piero Giovanni Luca Porta Mana; Gunnar Björk; Sergei Ya. Kilin; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bayesian probability theory; quantum theory; state assignment; state estimation; Physics; Fysik;

   Sammanfattning : The discipline usually called `probability theory' can be seen as the theory which describes and sets standard norms to the way we reason about plausibility. From this point of view, this `plausibility theory' is a province of logic, and the following informal proportion subsists: plausibility theory is to the common notion of `plausibility', as deductive logic is to the common notion of `truth'.

7. 5. Gaussian Bridges : Modeling and Inference

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

   Sammanfattning : 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. LÄS MER
