Laplacian U-Processes for Multiple Change-Point Detection in Dependent Text Networks: An Application to Historical Chinese Articles
Fanghua Chen, Yizhou Cai, Lu zhou +1
We propose a two-view weighted-concordance operator (WCO) framework for offline change-point detection in weakly dependent text networks. Weighted word-co-occurrence graphs yield f…
Voronoi-Elitism Genetic Algorithm: A Generic Derivative-Free Routine With Theory and Implementation for Statistical Optimization
Anthony Haitao Zou, Yizhou Jake Cai, Ting Fung Ma
In this paper, we propose a generic optimization approach for challenging objective functions that finds applications in various statistical problems. We focus on objective functio…
Stratified Bootstrap Test Package
Ehsan Mohammadi, Fanghua Chen, Yizhou Cai +3
The Stratified Bootstrap Test (SBT) provides a nonparametric, resampling-based framework for assessing the stability of group-specific ranking patterns in multivariate survey or ra…
Maximum Ideal Likelihood Estimation: A Unified Inference Framework for Latent Variable Models
Yizhou Cai, Ting Fung Ma
This paper develops a unified estimation framework, the Maximum Ideal Likelihood Estimation (MILE), for general parametric models with latent variables. Unlike traditional approach…
