Abstract:
Recently, a number of intriguing ideas that prioritize accuracy and speed—such as XGBoost, LightGBM, and CatBoost—have added to the family of gradient boosting algorithms. Scalable ensemble method XGBoost has proven to be a dependable and effective machine learning problem solution. LightGBM is a precise model that uses selective selection of high gradient cases to provide incredibly quick training performance. To increase the model's accuracy, CatBoost alters the gradient computation to prevent the prediction shift. This paper offers a useful examination of the performance of these unique gradient boosting variations in terms of training speed, generalization, and hyper-parameter configuration. Furthermore, a thorough comparison of gradient boosting, random forests, LightGBM, XGBoost, and random forests has been carried out utilizing both the models' default settings and highly calibrated models. Despite the few discrepancies, the comparison's findings show that CatBoost outperforms the other algorithms in terms of both AUC and generalization accuracy throughout the datasets under study. While LightGBM is the quickest approach available, it isn't the most precise. In terms of training speed and accuracy, XGBoost comes in second. Lastly, two new techniques are suggested and used to do a thorough examination of the impact of hyper-parameter adjustment in XGBoost, LightGBM, and CatBoost.
