Learnability and the Vapnik-Chervonenkis dimension

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.

Learning by canonical smooth estimation. II. Learning and choice of model complexity

TL;DR: This paper analyzes the properties of a procedure for learning from examples based on a canonical error estimator developed in Part I, and shows that for a broad class of learning problems, the set of cases for which such empirical error minimization works is a proper subset of the Cases for which the canonical learner works.

Using the Pseudo-Dimension to Analyze Approximation Algorithms for Integer Programming

TL;DR: Approximation guarantees for randomized algorithms for packing and covering integer programs expressed in certain normal forms are proved and applications are described to a generalization of Dominating Set motivated by distributed file sharing applications, to an optimization problem motivated by an analysis of boosting, and to ageneralization of matching in hypergraphs.
