PPT-Bayesian Networks

Alan Ritter Problem NonIID Data Most realworld data is not IID like coin flips Multiple correlated variables Examples Pixels in an image Words in a document Genes in a microarray We saw one example of how to deal with this. De64257nition A Bayesian nonparametric model is a Bayesian model on an in64257nitedimensional parameter space The parameter space is typically chosen as the set of all possi ble solutions for a given learning problem For example in a regression prob . Rebecca R. Gray, Ph.D.. Department of Pathology. University of Florida. BEAST:. is a cross-platform program for Bayesian MCMC analysis of molecular sequences. entirely orientated towards rooted, time-measured phylogenies inferred using strict or relaxed molecular clock models. P(. A . &. B. ) . = . P(. A. |. B. ) * P(. B. ). Product Rule:. Bayesian Reasoning. P(. A . &. B. ) . = . P(. A. |. B. ) * P(. B. ). Product Rule:. Shorthand for . . P(A=true & B=true) = P(A=true | B=true) * P(B=true). Bayesian Network Motivation. We want a representation and reasoning system that is based on conditional . independence. Compact yet expressive representation. Efficient reasoning procedures. Bayesian Networks are such a representation. Chris . Mathys. Wellcome Trust Centre for Neuroimaging. UCL. SPM Course (M/EEG).
