内容简介: Stochastic optimization is a mathematical framework that models decision making under uncertainty. It usually assumes that the decision maker has full knowledge about the underlying uncertainty through a known probability distribution and minimizes (or maximizes) a functional of the cost (or reward) function. However, the probability distribution of the randomness in the system is rarely known in practice and is often estimated from historical data. The goal of the decision maker is therefore to select the optimal decision under this distributional uncertainty. This talk aims to address the distributional uncertainty under different contexts of stochastic optimization by proposing new formulations and devising new approaches.
