Online change point detection under heavy-tailedness and contamination
Edwin Yiu Nam Tang, Yudong Chen, Mengchu Li +1
We study an online version of the robust mean change point detection problem under a dynamic Huber contamination model with arbitrary contamination distribution and inlier distribu…
Robust mean change point testing in high-dimensional data with heavy tails
Mengchu Li, Yudong Chen, Tengyao Wang +1
We study mean change point testing problems for high-dimensional data, with exponentially- or polynomially-decaying tails. In each case, depending on the -norm of the mean…
Network change point localisation under local differential privacy
Mengchu Li, Thomas B. Berrett, Yi Yu
Network data are ubiquitous in our daily life, containing rich but often sensitive information. In this paper, we expand the current static analysis of privatised networks to a dyn…
On robustness and local differential privacy
Mengchu Li, Thomas B. Berrett, Yi Yu
It is of soaring demand to develop statistical analysis tools that are robust against contamination as well as preserving individual data owners' privacy. In spite of the fact that…
