by Markov Chain Monte Carlo Sampling - a Bayesian approach, " In
Structural, Syntactic, and Statistical Pattern Recognition, Proceedings of the

We redefine the problem of feature selection as one of model selection and
propose to use a Markov Chain Monte Carlo method to sample models. The
applicability of our method is related to Bayesian network classifiers.
Simulation experiments indicate that our novel proposal distribution results in
an ignorant proposal prior. Finally, it is shown how the sampling can be
controlled by a regularization prior.
