Incremental Aggregation on the Grassmannian for Asynchronous Eigenspace Computation

Xiaolu Wang, Jiang Hu, Hoi-To Wai

We study asynchronous optimization for finite-sum eigenspace computation in heterogeneous distributed systems. The theoretical foundations for asynchronous eigenspace computation r…

A Retraction-free Method for Nonsmooth Minimax Optimization over a Compact Manifold

Necdet Serhat Aybat, Jiang Hu, Zhanwang Deng

We study the minimax problem $min_{x \in M} max_{y} f_{r} (x, y) := f (x, y) - h (y)$ , where $M$ is a compact submanifold, $f$ is continuously differentiable in $(x, y)$ , $h$ is a closed, weak…
