    A Decentralized Partially Observable Team Decision Methodology with Delayed Information Sharing

    Xiaoxing Ren, Thomas Parisini, Andreas A. Malikopoulos

    math.OC · cs.LG · eess.SY · stat.ML

    We study decentralized partially observable team decision problems with low-rank latent dynamics and unknown system models. The proposed framework combines team-theoretic equivalence with low-rank model representations to address cooperative decision-making in partially observable Markov decision processes without prior knowledge of the transition model. Each team member makes decisions based on local private information and delayed common...

    Polyak-Type Extragradient Methods for Monotone Root-Finding Problems

    TaeHo Yoon, Sayantan Choudhury, Ezra Greenberg, Nicolas Loizou

    math.OC · cs.LG

    We study Polyak-type step-size selection for extragradient methods for solving deterministic and stochastic monotone root-finding problems. We show that the known projection-type correction for deterministic extragradient arises from minimizing an upper bound on the distance to a solution, paralleling the classical Polyak step-size construction. Using this viewpoint, we provide a unified deterministic analysis of the Polyak-type Extragradient...
