Change-Point Detection With Multivariate Repeated Measures
Serim Han, Jingru Zhang, Hoseung Song
Graph-based methods have shown particular strengths in change-point detection (CPD) tasks for high-dimensional nonparametric settings. However, existing CPD research has rarely add…
Externally Validated Breast Ultrasound Segmentation via Multi-task Learning with BI-RADS-Consistent Morphological Priors
Jingru Zhang, Saed Moradi, Ashirbani Saha
External validation of breast ultrasound segmentation models remains limited because internal train--test splits do not capture domain shifts across imaging systems, acquisition pr…
A new non-parametric test for multivariate paired data from pair matching or paired designs
Jingru Zhang, Hao Chen, Xiao-Hua Zhou
In observational studies, achieving covariate balance in pair matching between treatment and control groups or exposed and unexposed groups is essential. This balance enables testi…
Graph-Based Two-Sample Tests for Data with Repeated Observations
Jingru Zhang, Hao Chen
In the regime of two-sample comparison, tests based on a graph constructed on observations by utilizing similarity information among them is gaining attention due to their flexibil…
