WebPAC-Bayes bounds are another expression of Occam’s razor where simpler descriptions of the data generalize better. While there has been progress in developing tighter PAC-Bayes bounds for deep neural networks, these bounds tend … WebChapter 6 PAC-Bayes bounds. The work presented here is also published in [35].. PAC-Bayes bounds are a generalization of the Occam’s razor bound for algorithms which output a distribution over classifiers rather than just a single classifier. This includes the possibility of a distribution over a single classifier, so it is a generalization.
