WebNov 20, 2024 · PAC-Bayes theory, known as generalization error bounds theory, provides a theoretical analysis framework for estimating the generalization performance of the machine learning model. With high probability, PAC-Bayes bound provides the numerical generalization error upper bound for a learnt model. WebThe standard PAC-Bayes bound uses a Gaussian prior centred at the origin in weight space. The key to the new bound is to use part of the training set to compute a more informative prior and then compute the bound on the remainder of the examples relative to this prior.
