TLDR
This paper shows that the essential condition for distribution-free learnability is finiteness of the Vapnik-Chervonenkis dimension, a simple combinatorial parameter of the class of concepts to be learned.
Abstract
Valiant's learnability model is extended to learning classes of concepts defined by regions in Euclidean space En. The methods in this paper lead to a unified treatment of some of Valiant's results, along with previous results on distribution-free convergence of certain pattern recognition algorithms. It is shown that the essential condition for distribution-free learnability is finiteness of the Vapnik-Chervonenkis dimension, a simple combinatorial parameter of the class of concepts to be learned. Using this parameter, the complexity and closure properties of learnable classes are analyzed, and the necessary and sufficient conditions are provided for feasible learnability.

Halfspace learning, linear programming, and nonmalicious distributions

TL;DR: It is proved that, in n dimensions, this linear programming algorithm due to Vaidya learns up to e accuracy with probability 1−e in O((n2/e) log2(n/e)+n3.38 log( n/e)) time, which compares favorably with the best known bound for the perceptron algorithm.

Optimal Quantum Sample Complexity of Learning Algorithms

TL;DR: In this article, it was shown that quantum and classical sample complexity are in fact equal up to constant factors in both the PAC and agnostic models, and that quantum examples are more powerful than classical examples in some fixed-distribution settings.
