arXiv:2604.18546v2 Announce Type: replace Abstract: We propose a distributionally robust approach to risk-sensitive estimation of an unknown signal x from an observed signal y. The observation and unknown signal are modeled as random vectors whose joint probability distribution is unknown, but assumed to belong to a given type-2 Wasserstein ball of distributions, termed the ambiguity set. The performance of an estimator is measured according to the conditional value-at-risk (CVaR) of the squared estimation error. Within this framework, we study the problem of computing affine estimators that m
The increasing complexity and uncertainty in modern AI systems necessitate robust estimation techniques to handle distributional shifts and risk effectively.
This research provides a foundational mathematical framework for developing more reliable and secure AI systems, especially in high-stakes applications where estimation errors have significant consequences.
The ability to build AI models that are inherently more resilient to unknown data distributions and explicitly account for risk, moving towards more dependable autonomous systems.
