In this work, the data is explored for particle identification task on LHCb detector and results are acquired for flatness boosting using gradient boosting models. I show that adding a flatness term in loss function of the model enhances its performance for high energy physics tasks and compare a set of models both with and without flatness loss. I also describe the existing particle identification systems and their features, show the improvement that can be achieved with modern supervised learning models and discuss following research.
