  2. 1. Optimisation of Clinical Trials using Bayesian Decision Theory

    Author : Sebastian Jobjörnsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; decision theory; drug regulation; ; Bayesian statistics; subgroup analysis; clinical trials; health economics; multiple testing; decision theory;

    Abstract : A decision maker confronted with the task of designing a clinical trial has to consider a multitude of aspects. Large trials lead to more evidence,which in turn makes it less likely that harmful decisions are taken when deciding on future treatments for patients. READ MORE

  4. 2. Bayesian Cluster Analysis : Some Extensions to Non-standard Situations

    Author : Jessica Franzén; Daniel Thorburn; Jukka Corander; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cluster analysis; Clustering; Classification; Mixture model; Gaussian; Bayesian inference; MCMC; Gibbs sampler; Deviant group; Longitudinal; Missing data; Multiple imputation; Statistics; Statistik; Statistics; statistik;

    Abstract : The Bayesian approach to cluster analysis is presented. We assume that all data stem from a finite mixture model, where each component corresponds to one cluster and is given by a multivariate normal distribution with unknown mean and variance. READ MORE

  5. 3. Efficient Bayesian Planning

    Author : Divya Grover; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; POMDP; Partially Observable MDP; Planning; Bayesian Reinforcement Learning;

    Abstract : Artificial Intelligence (AI) is a long-studied and yet very active field of research. The list of things differentiating humans from AI grows thinner but the dream of an artificial general intelligence remains elusive. READ MORE

  6. 4. Bayesian structure learning in graphical models

    Author : Felix Leopoldo Rios; Tatjana Pavlenko; Klas Markström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian statistics; graphical models; Bayesian networks; Markov networks; structure learning; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : This thesis consists of two papers studying structure learning in probabilistic graphical models for both undirected graphs anddirected acyclic graphs (DAGs).Paper A, presents a novel family of graph theoretical algorithms, called the junction tree expanders, that incrementally construct junction trees for decomposable graphs.
