Long-term effect estimation when combining clinical trial and observational follow-up datasets
Gang Cheng, Yen-Chi Chen, Joseph M. Unger +2
Combining experimental and observational follow-up datasets has received a lot of attention lately. In a time-to-event setting, recent work has used medicare claims to extend the f…
Efficient Community Detection in Large-Scale Dynamic Networks Using Topological Data Analysis
Wei Guo, Ruqian Chen, Yen-Chi Chen +1
In this paper, we propose a method that extends the persistence-based topological data analysis (TDA) that is typically used for characterizing shapes to general networks. We intro…
Statistical Inference Using Mean Shift Denoising
Yunhua Xiang, Yen-Chi Chen
In this paper, we study how the mean shift algorithm can be used to denoise a dataset. We introduce a new framework to analyze the mean shift algorithm as a denoising approach by v…
Generalized Mode and Ridge Estimation
Yen-Chi Chen, Christopher R. Genovese, Larry Wasserman
The generalized density is a product of a density function and a weight function. For example, the average local brightness of an astronomical image is the probability of finding a…
