Graph-Split Bayesian Causal Forest for Spatial Heterogeneous Treatment Effect Estimation
Shuren He, Huiyan Sang, Ligang Lu
In spatial observational studies, treatment assignment and outcomes often exhibit spatial dependence patterns, and treatment effects may vary across space and subpopulations due to…
Consistent Bayesian Local Spatial Feature Selection with Application to Spatial Multimodal Omics
Kun Huang, Xiyu Peng, Huiyan Sang +1
Motivated by a high-dimensional regression problem in spatial multimodal omics (SMO), we propose a Bayesian framework for local spatial feature selection, where a random domain par…
GS-BART: Bayesian Additive Regression Trees with Graph-split Decision Rules
Shuren He, Huiyan Sang, Quan Zhou
Ensemble decision tree methods such as XGBoost, Random Forest, and Bayesian Additive Regression Trees (BART) have gained enormous popularity in data science for their superior perf…
SBAMDT: Bayesian Additive Decision Trees with Adaptive Soft Semi-multivariate Split Rules
Stamatina Lamprinakou, Huiyan Sang, Bledar A. Konomi +1
Bayesian Additive Regression Trees [BART, Chipman et al., 2010] have gained significant popularity due to their remarkable predictive performance and ability to quantify uncertaint…
