Detecting Backdoors During the Inference Stage Based on Corruption Robustness Consistency … Web1.We present a novel optimization-based approach for scenario reduction for two-stage stochastic optimization problems. As part of this approach, we introduce a quantity we term as \Problem-dependent divergence" that takes into account the quality of decisions induced by two discrete distributions, and generalizes the Wasserstein distance.
