Quickest Causal Change Point Detection by Adaptive Intervention
Haijie Xu, Chen Zhang
We propose an algorithm for change point monitoring in linear causal models that accounts for interventions. Through a special centralization technique, we can concentrate the chan…

Partially-Observable Sequential Change-Point Detection for Autocorrelated Data via Upper Confidence Region
Haijie Xu, Xiaochen Xian, Chen Zhang +1
Sequential change point detection for multivariate autocorrelated data is a very common problem in practice. However, when the sensing resources are limited, only a subset of varia…
