Free shipping for many products! Webbname \Probably Approximately Correct" comes from the fact that we want a hypothesis that is approximately correct ( -good) with high probability (namely 1 ). The probability is taken over the choice of S, which will determine which hthe algorithm chooses. This is a reasonable goal because there is always a small chance that the test data will ...

WebbL' apprentissage PAC (pour probably approximately correct en anglais) est un cadre théorique pour l' apprentissage automatique. Il permet notamment d'évaluer la difficulté d'un problème dans le contexte de l' apprentissage supervisé. Il a été proposé par Leslie Valiant en 1984. Principe [ modifier modifier le code]

It was proposed in 1984 by Leslie Valiant. In this framework, the learner receives samples and must select a generalization function (called the hypothesis) from a certain … Visa mer In order to give the definition for something that is PAC-learnable, we first have to introduce some terminology. For the following definitions, two examples will be used. The first is the problem of Visa mer Under some regularity conditions these conditions are equivalent: 1. The concept class C is PAC learnable. 2. The VC dimension of C is finite. 3. C is a uniformly Glivenko-Cantelli class. Visa mer • M. Kearns, U. Vazirani.
