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.

Multiple Comparisons in Induction Algorithms

TL;DR: This work analyzes the statistical properties of MCPs and shows how failure to adjust for these properties leads to the pathologies of induction algorithms, including attribute selection errors, overfitting, and oversearching.

An Efficient Membership-Query Algorithm for Learning DNF with Respect to the Uniform Distribution

TL;DR: The strong learning algorithm utilizes one of Freund's boosting techniques and relies on the fact that boosting does not require a completely distribution-independent weak learner, and it is shown that DNF is weakly learnable with respect to uniform from noisy examples.
