Interactive Combinatorial Bandits: Balancing Competitivity and Complementarity

no code implementations7 Jul 2022 Adhyyan Narang, Omid Sadeghi, Lillian J Ratliff, Maryam Fazel, Jeff Bilmes

We are motivated by applications where there is a natural complementarity between certain elements: e. g., in a movie recommendation system, watching the first movie in a series complements the experience of watching a second (and a third, etc.).

Global Convergence to Local Minmax Equilibrium in Classes of Nonconvex Zero-Sum Games

no code implementations NeurIPS 2021 Tanner Fiez, Lillian J Ratliff, Eric Mazumdar, Evan Faulkner, Adhyyan Narang

For the class of nonconvex-PL zero-sum games, we exploit timescale separation to construct a potential function that when combined with the stability characterization and an asymptotic saddle avoidance result gives a global asymptotic almost-sure convergence guarantee to a set of the strict local minmax equilibrium.
