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.

Lower bounds on learning decision lists and trees

TL;DR: In this paper, it was shown that decision trees are not PAC-learnable and that decision lists can not be learned as efficiently as k-decision lists and decision trees, thus disproving a claim in a popular textbook.

Learning privately with labeled and unlabeled examples

TL;DR: In this paper, the authors show that the labeled sample complexity of private semi-supervised learners is characterized by the VC dimension of the concept class, and that the unlabeled sample complexity is as big as the representation length of domain elements.

Fast vertex guarding for polygons with and without holes

TL;DR: This paper observes that, since minimum visibility decompositions for simple polygons have only O(n^2) sinks (i.e., cells of minimal visibility) (Bose et al., 2000), the running time of the algorithm can be further improved to O( n^3), and shows that it can attain approximation factors of O(loglogopt) forsimple polygons and O((1+log(h+1))log opt) for polygons with holes.

Knowledge Infusion: In Pursuit of Robustness in Artificial Intelligence

TL;DR: In knowledge infusion rules are learned from the world in a principled way so that sub- sequent reasoning using these rules will also be principled, and subject only to errors that can be bounded in terms of the inverse of the effort invested in the learning process.
