THE MLP-MC-4 METHOD Regression and classification with multilayer perceptron networks trained by Bayesian methods using Markov chain Monte Carlo without Automatic Relevance Determination (ARD) without direct linear connections Radford M. Neal, 28 July 1997 This method is the same as mlp-mc-2, except that direct linear connections from inputs to outputs are omitted, and Automatic Relevance Determination is not used. It can also be compared to mlp-mc-3, which omits the direct connections, but does do Automatic Relevance Determination.
