WebThe paper investigates the connection between PAC-Bayes and Rademacher complexities, two framework in statistical learning theory to upper bound the generalization error of predictors. The paper is quite pleasant to read, and clarity is remarkable. WebWe demonstrate an easy learning task which is not amenable to a PAC-Bayes analysis. Speciﬁcally, we consider the task of linear classiﬁcation in 1D; it is well-known that this task is learnable using just O(log(1= )= ) examples. On the other hand, we show that this fact can not be proved using a PAC-Bayes analysis: for any

Web（2）PAC-Bayes meta-learning bounds: A related approach for deriving such bounds is based on PAC-Bayes theory. First proposed in the meta-learning framework in the pioneering paper of [1], this idea of learning a hyper-posterior that generates a prior for the new task has been taken up several times in the recent years [2-9]. WebPAC-Bayes is a generic framework to efﬁciently rethink generalization for numerous machine learning algorithms. It leverages the ﬂexibility of Bayesian learning and allows …
