Stochastic Optimization of PCA with Capped MSG [PDF]
, 2013 We study PCA as a stochastic optimization problem and propose a novel stochastic approximation algorithm which we refer to as "Matrix Stochastic Gradient" (MSG), as well as a practical variant, Capped MSG.

Stochastic-Constrained Stochastic Optimization with Markovian Data
, 2023 This paper considers stochastic-constrained stochastic optimization where the stochastic constraint is to satisfy that the expectation of a random function is below a certain threshold. In particular, we study the setting where data samples are drawn from a Markov chain and thus are not independent and identically distributed.

Analysis of Individual Convergence Bound for Gradient Biased Stochastic DA Optimization Method [PDF]
Jisuanji gongcheng, 2019 Samples that do not satisfy the independent and identical distribution will lead to deviations of the gradient estimation in the iterative process,and the convergence bound of the optimal individual cannot be determined under the interference of noise ...
