Quantile Encoder: Tackling High Cardinality Categorical Features in Regression Problems

May 6, 2022

In this paper, we provide an in-depth analysis of how to tackle high cardinality categorical features with the quantile. Our proposal outperforms state-of-the-art encoders, including the traditional statistical mean target encoder, when considering the Mean Absolute Error, especially in the presence of long tailed or skewed distributions.
