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.

Leva: Boosting Machine Learning Performance with Relational Embedding Data Augmentation

TL;DR: Lva builds a relational embedding by representing relational data as a graph and then using embedding methods to represent the graph as vectors, and it is shown that the supervision signal from the downstream task filters out information that is not useful.
