Bandit Change-Point Detection for Real-Time Monitoring High-Dimensional Data Under Sampling Control
Wanrong Zhang, Yajun Mei
In many real-world problems of real-time monitoring high-dimensional streaming data, one wants to detect an undesired event or change quickly once it occurs, but under the sampling…
An elementary approach for minimax estimation of Bernoulli proportion in the restricted parameter space
Heejune Sheen, Yajun Mei
We present an elementary mathematical method to find the minimax estimator of the Bernoulli proportion under the squared error loss when belongs to the restricted parameter…
Rapid Detection of Hot-spots via Tensor Decomposition with applications to Crime Rate Data
Yujie Zhao, Hao Yan, Sarah Holte +1
We propose an efficient statistical method (denoted as SSR-Tensor) to robustly and quickly detect hot-spots that are sparse and temporal-consistent in a spatial-temporal dataset th…
Rapid Detection of Hot-spot by Tensor Decomposition with Application to Weekly Gonorrhea Data
Yujie Zhao, Hao Yan, Sarah E. Holte +2
In many bio-surveillance and healthcare applications, data sources are measured from many spatial locations repeatedly over time, say, daily/weekly/monthly. In these applications,…
