CatBoost is a machine learning method based on gradient boosting over decision trees.

Main advantages of CatBoost:

• Superior quality compared with other GBDT libraries on many datasets.
• Best-in-class prediction speed.
• Support for both numerical and categorical features.
• Fast GPU and multi-GPU support for out-of-the box training.
• Built-in visualization tools.
• Fast and reproducible distributed training with Apache Spark and CLI.
