The Impact of Batch Effect and Batch Adjustment on Predictive Model Performances

This project focuses on how batch effect and its adjustment influence the accuracy of classification models. I simulate expression datasets with differences in mean and variance across batches, and use ComBat for batch correction. Then I validate multiple commonly-used classification models on the data before and after the adjustment. I investigate their performance change on the data with and without batch correction, and try to search for or develop a model which stays robust to batch effect in its prediction performance.
