Multiplicative Optimism for Constant Regret in Games

This work introduces Multiplicatively Optimistic Regret Matching (MORM), an uncoupled learning rule for finite general-sum games that combines a potential-based regret-matching argument with multiplicative stability and Hellinger control of strategy movement.

Efficient Learning and Symmetry Discovery under Exact Invariances

This paper presents the first polynomial-time algorithm for learning with exact group invariances that applies uniformly to finite and infinite groups, and shows that exact symmetries can be identified from data and exploited for learning in polynomial time.
