Learning a Gradient-free Riemannian Optimizer on Tangent Spaces

2021 · Proceedings of the AAAI Conference on Artificial Intelligence

A principal way of addressing constrained optimization problems is to model them as problems on Riemannian manifolds. Recently, Riemannian meta-optimization provides a promising way for solving constrained optimization problems by learning optimizers on Riemannian manifolds …
