This framework quantitatively embodies 'Occam's razor'. Over-complex and under-regularised models are automatically inferred to be less probable, even though their flexibility allows them to fit the data better. When applied to 'neural networks', the Bayesian framework makes possible 1 objective comparison of solutions using alternative network architectures; 2 objective stopping rules for network Bayesian thesis or growing procedures; 3 objective choice of type of weight decay terms or regularisers ; 4 on-line techniques for optimising weight decay or regularisation constant magnitude; 5 a measure of the effective number of well-determined parameters in a model; 6 quantified estimates of the error bars on network parameters and on network output.

In the case of classification models, it is shown that the careful incorporation of error bar information into a classifier's predictions yields improved performance.

Comparisons of the inferences of the Bayesian Framework with more traditional cross-validation methods help detect poor underlying assumptions in learning models.

The relationship of the Bayesian learning framework to 'active learning' is examined. Objective functions are discussed which measure the expected informativeness data measurements, in the context of both interpolation and classification problems. The concepts and methods described in this thesis are quite general and will be applicable to other data modelling problems whether they involve regression, classification or density dynamic Bayesian network ..

The approach used in this thesis is somewhat similar to Gelman et al.4 Estimation of Bayesian Logistic Regression Models Chapter 6 study are the regression coe cients for the Bayesian logistic regression models. no exact de nition for well-identi ed parameters or large sample size exist. In this thesis a new method is proposed to estimate major periods of migration from one region into another using phased, non-recombined sequence data from the present. The assumption is made that migration occurs in multiple waves and that during each migration period, a number of sequences, called `founder sequences', migrate into the new region.
