1. 1. Mean Field Games for Jump Non-Linear Markov Process

   Författare :Rani Basna; Astrid Hilbert; Rainer Buckdahn; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mean-field games; Optimal Control; Non-linear Markov Processes; Mathematics; Matematik;

   Sammanfattning : The mean-field game theory is the study of strategic decision making in very large populations of weakly interacting individuals. Mean-field games have been an active area of research in the last decade due to its increased significance in many scientific fields. LÄS MER

3. 2. The Final Size of Multitype Chain-Binomial Epidemic Processes

   Författare :Mikael Andersson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multitype epidemic process; counting process; Markov process; weak convergence; counting process;

   Sammanfattning : A multitype chain-binomial epidemic process is defined for a closed finite population by sampling a simple multidimensional counting process at certain points. The final size of the epidemic is then characterised, given the counting process, as the smallest root of a non-linear system of equations. LÄS MER

4. 3. Accelerating Monte Carlo methods for Bayesian inference in dynamical models

   Författare :Johan Dahlin; Thomas B. Schön; Fredrik Lindsten; Richard Everitt; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computational statistics; Monte Carlo; Markov chains; Particle filters; Machine learning; Bayesian optimisation; Approximate Bayesian Computations; Gaussian processes; Particle Metropolis-Hastings; Approximate inference; Pseudo-marginal methods;

   Sammanfattning : Making decisions and predictions from noisy observations are two important and challenging problems in many areas of society. Some examples of applications are recommendation systems for online shopping and streaming services, connecting genes with certain diseases and modelling climate change. LÄS MER

5. 4. Spatial Mixture Models with Applications in Medical Imaging and Spatial Point Processes

   Författare :Anders Hildeman; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Non-Gaussian; Bayesian level set inversion; Point processes; Substitute CT; Finite mixture models; Spatial statistics; Gaussian fields; Non-Gaussian;

   Sammanfattning : Finite mixture models have proven to be a great tool for both modeling non-standard probability distributions and for classification problems (using the latent variable interpretation). In this thesis we are building spatial models by incorporating spatially dependent categorical latent random fields in a hierarchical manner similar to that of finite mixture models. LÄS MER

7. 5. Dynamic single-cell modelling of nutrient signalling in budding yeast

   Författare :Sebastian Persson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nutrient signalling; single-cell; mixed-effects models; stochastic dynamic models; Bayesian inference;

   Sammanfattning : To survive in environments with constantly changing nutrient levels the bud- ding yeast Saccharomyces cerevisiae has a sophisticated nutrient sensing system. A central component of this system is the SNF1 signalling pathway, which primarily helps yeast adapt to glucose limited conditions. LÄS MER
