Description

Machine Learning (ML) have been widely applied in the High Energy Physics (HEP) to help physical community to solve complex problem in classification and analysis. Here we describe application of ML to solve the problem of classification background and signal events in DEAP-3600 experiment (SNOLAB, Canada) that constructed to search WIMP particles. We apply Boosted Decision Trees (BDT) method of ML, which upgraded by using Extra Trees and eXtra Gradient boosting method (XGBoost).
