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.

Repairing Decision-Making Programs Under Uncertainty

TL;DR: In this paper, the authors propose distribution-guided inductive synthesis, a repair technique that iteratively samples a finite set of inputs from a probability distribution defining the precondition, synthesizes a minimal repair to the program over the sampled inputs using an smt-based encoding, and verifies that the resulting program is correct and is semantically close to the original program.

PAC-like upper bounds for the sample complexity of leave-one-out cross-validation

TL;DR: This paper addresses the following question: if the authors have n training examples what is the probability that the leave-one-out cross-validation estimate differs from the actual error probability by more than a constant c?

Learning and decision-making in the framework of fuzzy lattices

TL;DR: A novel theoretical framework is delineated for supervised and unsupervised learning, called framework of fuzzy lattices, which suggests mathematically sound tools for dealing separately and/or jointly with disparate types of data including vectors of numbers, fuzzy sets, symbols, etc.

Pattern classification and scene analysis

TL;DR: In this article, a unified, comprehensive and up-to-date treatment of both statistical and descriptive methods for pattern recognition is provided, including Bayesian decision theory, supervised and unsupervised learning, nonparametric techniques, discriminant analysis, clustering, preprosessing of pictorial data, spatial filtering, shape description techniques, perspective transformations, projective invariants, linguistic procedures, and artificial intelligence techniques for scene analysis.
