In 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. In this framework, the learner receives samples and must select a generalization function (called the hypothesis) from a certain … See more 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 See more 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.
