Smooth Learning with Hard Constraints via Legendre-Regularized Policies

Zikun Lin, Rui Chen, Yijie Wang

We revisit contextual optimization from the perspective of policy class design. A desirable policy class should be expressive enough to learn rich context-decision relationships, s…

Distributionally Robust Performative Optimization

Zhuangzhuang Jia, Yijie Wang, Roy Dong +1

In performative stochastic optimization, decisions can influence the distribution of random parameters, rendering the data-generating process itself decision-dependent. In practice…
