Class-conditioned Domain Generalization via Wasserstein Distributional Robust Optimization

2021 · arXiv (Cornell University)

Given multiple source domains, domain generalization aims at learning a universal model that performs well on any unseen but related target domain. In this work, we focus on the domain generalization scenario where domain shifts …

Sequential Change Detection With Differential Privacy

2025 · IEEE Transactions on Information Theory

Sequential change detection is a fundamental problem in statistics and signal processing, with the CUSUM procedure widely used to achieve minimax detection delay under a prescribed false-alarm rate when pre- and post-change distributions are fully …
