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. WebMore precisely, PAC-Bayes learning exploits the Bayesian paradigm of explaining a learning problem through a meaningful distribution over a space of candidate predictors [see e.g. Maurer, 2004, Catoni, 2007, Tolstikhin and Seldin, 2013, Mhammedi et al., 2024]. An active line of research in PAC-Bayes learning is to
Machine learning theory - PAC-Bayesian Theory
WebAbstract. This paper gives PAC guarantees for “Bayesian” algorithms—algorithms that optimize risk minimization expressions involving a prior probability and a likelihood for the training data. PAC-Bayesian algorithms are motivated by a desire to provide an informative prior encoding information about the expected experimental setting but ... WebIn computational learning theory, probably approximately correct ( PAC) learning is a framework for mathematical analysis of machine learning. It was proposed in 1984 by Leslie Valiant. [1] In this framework, the learner receives samples and must select a generalization function (called the hypothesis) from a certain class of possible functions. commandos clothing
(PDF) A Primer on PAC-Bayesian Learning - ResearchGate
WebI A PAC-Bayesian approach bases the bias of the learning algorithm on an arbitrary prior distribution, thus allowing the incorporation of domain knowledge, and yet provides … WebPAC-Bayes is a generic framework to efficiently rethink generalization for numerous machine learning algorithms. It leverages the flexibility of Bayesian learning and allows … WebAbstract. Most PAC-Bayesian bounds hold in the batch learning setting where data is collected at once, prior to inference or prediction. This somewhat departs from many contemporary learning problems where data streams are collected and the algorithms must dynamically adjust. We prove new PAC-Bayesian bounds in this online learning … commandos complete edition download
