New paper details SoS degree barriers in robust halfspace learning

By PulseAugur Editorial · [2 sources] ·

A new research paper introduces a characterization of Sum-of-Squares (SoS) degree barriers within the Reweighted-Hinge method for robust halfspace learning. The study, which focuses on learning under malicious noise, establishes a principle where the maximal corruption mass that can hide from a certificate is directly related to the Christoffel function of the clean marginal. This leads to a margin-degree tradeoff, a specific degree-2 outlier barrier, and a degree-2t algorithm that traces a performance frontier. AI
