Overview

What is CatBoost?

CatBoost is a general-purpose gradient boosting library that supports categorical features out of the box. It offers fast inference and can run on CPU or GPU, including multi-GPU setups.

Key differentiator

CatBoost stands out with its native support for categorical features, making it particularly effective in scenarios where feature preprocessing would otherwise be complex or time-consuming.
