Riemannian Newton Methods with Statistical Inference
Xiaotian Chang, Qirui Hu, Yangdi Jiang +1
We develop online statistical inference for Polyak-Ruppert averages of inexact Newton iterates on Riemannian manifolds. A local asymptotic representation separates observation nois…

Bootstrap Inference for Riemannian Optimization Problems
Xiaotian Chang, Qirui Hu, Yangdi Jiang +1
We develop an online multiplier bootstrap for manifold-valued parameters estimated by averaging the iterates of Riemannian stochastic approximation. The method runs weighted iterat…
