Witryna31 paź 2024 · CatBoost is a great alternative to XGBoost. It should be your choice if you have a large dataset with categorical variables. When we consider the performance and execution time, CatBoost can outperform XGBoost. But, LightGBM is much better than CatBoost! This is the end of today’s post. WitrynaMy guess is that the biggest effect comes from the fact that XGBoost uses an approximation on the split points. If you have a continuous feature with 10000 possible splits, XGBoost consider only "the best" 300 splits by default (this is a simplification).
