We often encode categorical columns with one-hot encoding. But the feature matrix becomes sparse and unmanageable with many categories.

The category-encoders library provides a suite of encoders specifically for categorical variables. This makes it effortless to experiment with various encoding techniques.

For instance, I used its binary encoder above to represent a categorical column in binary format.
