New research explores Wasserstein DRO for risk-sensitive estimation and regret optimization

By PulseAugur Editorial · [2 sources] ·

Two new research papers explore the application of Wasserstein distributionally robust optimization (DRO) in different machine learning contexts. The first paper introduces a method for risk-sensitive estimation using Wasserstein balls and conditional value-at-risk (CVaR), demonstrating its effectiveness in electricity price forecasting. The second paper focuses on regret optimization within Wasserstein ambiguity sets, proposing a theory and algorithms to balance robustness with potential gains, even in complex scenarios where computation is NP-hard.
