PAC-Bayes Analysis Of Maximum Entropy Learning
John S. Shawe-Taylor, David Roi Hardoon · 2009
We extend and apply the PAC-Bayes theorem to the analysis of maximum entropy learning by considering maximum entropy classification. The theory introduces a multiple sampling technique that controls an effective margin of the bound. We further develop a dual implementation of the convex optimisation that optimises the bound. This algorithm is tested on some simple datasets and the value of the bound compared with the test error.© 2009 by the authors.
