- This repo contains code for experimenting with categorical encoding - WoE, Catboost, Target encoder and many more.
- Many of these encoders such as Catboost, Target, Leave-one-out are very popular when it comes to encoding a categorical variable with very high cardinlaity.
- WoE is very popular for low/high cardinality for Binary classification problem especially with Logistic Regression.
- Binary and Ordinal encoder could be useful when encoding an ordinal variable.
- The train and test data used in these notebooks can be found here: https://www.kaggle.com/c/cat-in-the-dat/data/.
