Online detection of cascading change-points
Rui Zhang, Yao Xie, Rui Yao +1
We propose an online detection procedure for cascading failures in the network from sequential data, which can be modeled as multiple correlated change-points happening during a sh…
Sequential Adversarial Anomaly Detection for One-Class Event Data
Shixiang Zhu, Henry Shaowu Yuchi, Minghe Zhang +1
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 solv…
Spectral CUSUM for Online Network Structure Change Detection
Minghe Zhang, Liyan Xie, Yao Xie
Detecting abrupt changes in the community structure of a network from noisy observations is a fundamental problem in statistics and machine learning. This paper presents an online…
Goodness-of-fit tests on manifolds
Alexander Shapiro, Yao Xie, Rui Zhang
We develop a general theory for the goodness-of-fit test to non-linear models. In particular, we assume that the observations are noisy samples of a submanifold defined by a \yao{s…
Imitation Learning of Neural Spatio-Temporal Point Processes
Shixiang Zhu, Shuang Li, Zhigang Peng +1
We present a novel Neural Embedding Spatio-Temporal (NEST) point process model for spatio-temporal discrete event data and develop an efficient imitation learning (a type of reinfo…
Asynchronous Multi-Sensor Change-Point Detection for Seismic Tremors
Liyan Xie, Yao Xie, George V. Moustakides
We consider the sequential change-point detection for asynchronous multi-sensors, where each sensor observe a signal (due to change-point) at different times. We propose an asynchr…
