CatBoost is a machine learning method based on gradient boosting over decision trees.
Main advantages of CatBoost:
- Superior quality when compared with other GBDT libraries.
- Best in class inference speed.
- Support for both numerical and categorical features.
- Fast GPU and multi-GPU support for training (compiled binaries and python package for learning on one host, build cmd-line MPI version from source to learn on several GPU machines).
- Data visualization tools included.
