New method for asynchronous eigenspace computation on Grassmannian

By PulseAugur Editorial · [1 sources] ·

This paper introduces a novel method for asynchronous eigenspace computation in distributed systems, focusing on the Grassmannian manifold. The proposed Grassmannian incremental aggregation technique minimizes per-update costs by refreshing only arriving components and reusing cached gradients, thus avoiding global synchronization. The method utilizes an extrinsic polar update to maintain intrinsic subspace geometry and offers a two-phase linear convergence characterized by broad-basin and local regimes, demonstrating improved sample efficiency and wall-clock convergence in experiments on principal component analysis.
