Second, we develop a regularization scheme for MAML [25] that explicitly minimizes the derived bound (Algorithm 1). We refer to the resulting approach as PAC-BUS since it combines PAC-Bayes and Uniform Stability to derive generalization guarantees for meta-learning.

PAC-Bayes Learning Bounds for Sample-Dependent Priors

WebSimilarly, single-draw PAC-Bayes bounds ensure that gen(W;S) ( with probability no greater than1) 2(0;1). These concentration bounds are of high probability when the dependency on 1 is logarithmic, i.e., log(1= ). See, [27, 2] for an overview. The bounds from this work may be used to obtain single-draw PAC-Bayes bounds applying Markov’s WebFor sake of completeness, we also provide a PAC-Bayes bound for stationary ϕ-mixing processes; it is based on a different approach and its presentation is postponed to the appendix together with the tools that allows us to derive it. 1.4 Organization of the Paper The paper is organized as follows.

WebDec 7, 2024 · We next use a function-based picture to derive a marginal-likelihood PAC-Bayesian bound. This bound is, by one definition, optimal up to a multiplicative constant in the asymptotic limit of large training sets, as long as the learning curve follows a power law, which is typically found in practice for deep learning problems.
