11. Machine learning using approximate inference : Variational and sequential Monte Carlo methods
Sammanfattning : Automatic decision making and pattern recognition under uncertainty are difficult tasks that are ubiquitous in our everyday life. The systems we design, and technology we develop, requires us to coherently represent and work with uncertainty in data. LÄS MER
12. Markov chain Monte Carlo for rare-event simulation in heavy-tailed settings
Sammanfattning : .... LÄS MER
13. On Perfect Simulation of Markovian Queueing Networks with Blocking
Sammanfattning : Perfect simulation of a class of Markovian queueing networks with finite buffers is examined in this monograph. The network processes defined are modelled by restricted multivariate birth and death processes with intensities depending on a random environment. The random environments are mainly a set of independent onoff processes. LÄS MER
14. Spatio-Temporal Estimation for Mixture Models and Gaussian Markov Random Fields - Applications to Video Analysis and Environmental Modelling
Sammanfattning : In this thesis computationally intensive methods are used to estimate models and to make inference for large, spatio-temporal data sets. The thesis is divided into two parts: the first two papers are concerned with video analysis, while the last three papers model and investigate environmental data from the Sahel area in northern Africa.

15. Inference in a Partially Observed Percolation Process
Sammanfattning : In this licentiate thesis, inference in a partially oberved percolation process living on a graph, is considered. Each edge of the graph is declared open with probability $\theta$ and closed with probability $1-\theta$ independently of the states of all other edges. LÄS MER
