TLDR

This paper shows that high-arity sample compression schemes imply high-arity PAC learnability, extending learning theory to product spaces.

Key contributions

  • Introduces the concept of high-arity sample compression schemes.
  • Demonstrates that high-arity sample compression implies high-arity PAC learnability.
  • Extends fundamental learning theory concepts to high-arity product spaces.

Why it matters

This work is crucial for advancing high-arity learning theory, an emerging field for product spaces. It establishes a fundamental link between sample compression and PAC learnability in this new context, deepening our theoretical understanding of learning.

Original Abstract

Recently, a series of works have started studying variations of concepts from learning theory for product spaces, which can be collected under the name high-arity learning theory. In this work, we consider a high-arity variant of sample compression schemes and we prove that the existence of a high-arity sample compression scheme of non-trivial quality implies high-arity PAC learnability.
