Analysis of stochastic approximation schemes with set-valued maps in the absence of a stability guarantee and their stabilization

Vinayaka G. Yaji, Shalabh Bhatnagar ยท 2017

In this paper, we analyze the behavior of stochastic approximation schemes with set-valued maps in the absence of a stability guarantee. We prove that after a large number of iterations if the stochasโ€ฆ
