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…

Worth Their Weight: Randomized and Regularized Block Kaczmarz Algorithms without Preprocessing

Gil Goldshlager, Jiang Hu, Lin Lin

Due to the ever growing amounts of data leveraged for machine learning and scientific computing, it is increasingly important to develop algorithms that sample only a small portion…
