New research links Galois theory to optimal machine learning strategies

By PulseAugur Editorial · [1 sources] ·

A new research paper explores the theoretical underpinnings of learning group elements from their actions, drawing connections between Galois theory and machine learning concepts like empirical risk minimization (ERM). The study establishes that for certain group structures, ERM is an optimal learning strategy, achieving the best possible sample complexity. It also introduces a new invariant, the Natarajan dimension, which is shown to coincide with group-theoretic properties for solvable Galois groups, and identifies the A5 group as the smallest group exhibiting a gap between these dimensions.

    Learning a Group Element from Its Action: Galois Correspondences, Optimal ERM, and an Abel-Ruffini Threshold for the Natarajan Dimension

    arXiv:2610.18154v1 Announce Type: cross Abstract: We study learning an unknown element $g$ of a group acting with finite orbits on a countable set, from examples $(x,gx)$. After a sample on $A$, the consistent hypotheses are the restrictions of a coset of the pointwise stabilizer…
