Main advantages of CatBoost: -------------- - Superior quality when [compared](https://github.com/catboost/benchmarks/blob/master/README.md) with other GBDT libraries on many datasets. - Best in class [prediction](https://catboost.ai/docs/concepts/c-plus-plus-api.html) speed. - Support for both [numerical and categorical](https://catboost.ai/docs/concepts/algorithm-main-stages.html) features. - Fast GPU and multi-GPU support for training out of the box. - Visualization tools [included](https://catboost.ai/docs/features/visualization.html). - Fast and reproducible distributed training with [Apache Spark](https://catboost.ai/en/docs/concepts/spark-overview) and [CLI](https://catboost.ai/en/docs/concepts/cli-distributed-learning).
