A search for tWZ production in the trilepton channel using Run 2 data from the ATLAS experiment
… the use of the Gradient Boosted Decision Tree (GBDT) machine learning algorithm. First, a hadronically-decaying W boson candidate was identified using a GBDT; this was used to suppress WZ background events. Then, an event-level GBDT was used to suppress all background events. A maximum …

Understanding travel mode choice: A new approach for city scale simulation
… Firstly, the Gradient Boosting Decision Trees (GBDT) model is the highest performing classifier for this task. Secondly, the relative differences in predictive performance between classifiers are far smaller than has been suggested by previous research. In particular, there is a much smaller …

Structure Function Relation of Porous 2D Material via SGCMC Simulation and Statistical Models
… model to be a Gradient Boosting Decision Trees (GBDT) regression model, whose out-of-sample R2 is 0.904, as opposed to the baseline model of linear regression with the porosity, whose out-of-sample R2 is 0.752.

Gradient Boosted Decision Tree Application to Muon Identification in the KLM at Belle II
We present the results of applying a Fast Boosted Decision Tree (FBDT) algorithm to the task of distinguishing muons from pions in K-Long and Muon (KLM) detector of the Belle II experiment. Performance was evaluated over a momentum range of 0.6 < p < 5.0 GeV/c by plotting Receiver Operating …
