"Parameter estimation for complex models"
D.M. Titterington
University of Glasgow
The talk will consider difficulties that arise in the analysis of
incomplete data. In principle, maximum likelihood or Bayesian
inference can be carried out, using tools such as the EM algorithm and
Gibbs sampling, but even these can become unwieldy or
sometimes impractical. Particular emphasis will be laid on
labour-saving approximations, such as the variational approximations
that have recently been described in the neural-computing literature.
Models that will be discussed include simple mixture
models and the hidden Markov random field models used in the statistical
analysis of noisy images.
All welcome!!
