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 … 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. Visa mer • M. Kearns, U. Vazirani. An Introduction to Computational Learning Theory. MIT Press, 1994. A textbook. • M.

Webb29 jan. 2024 · σ = √np (1-p) It turns out that if n is sufficiently large then we can actually use the normal distribution to approximate the probabilities related to the binomial distribution. This is known as the normal approximation to the binomial. For n to be “sufficiently large” it needs to meet the following criteria: np ≥ 5. n (1-p) ≥ 5. Webb4 jan. 2024 · Approximately learning concepts with high probability has first been introduced in the seminal work by Valiant [valiant84learnable]. From this starting point, probably approximately correct learning has come a long way and has been applied in a variety of use-cases.
