Bayesian Uncertainty Quantification for Low-Rank Matrix Completion

no code implementations5 Jan 2021 Henry Shaowu Yuchi, Simon Mak, Yao Xie

We consider the problem of uncertainty quantification for an unknown low-rank matrix $\mathbf{X}$, given a partial and noisy observation of its entries.

Sequential Adversarial Anomaly Detection for One-Class Event Data

no code implementations21 Oct 2019 Shixiang Zhu, Henry Shaowu Yuchi, Minghe Zhang, Yao Xie

We consider the sequential anomaly detection problem in the one-class setting when only the anomalous sequences are available and propose an adversarial sequential detector by solving a minimax problem to find an optimal detector against the worst-case sequences from a generator.
