BinaryEncoder assigns labels starting from 1

2

I'm trying to encode some categorical variables and I found that I'm getting too much dimensions due to BinaryEncoder starting labeling from 1 instead of 0. I'm working on the...

Hi. I would like to propose an enhancement for OrdinalEncoder, although it may also be relevant for other encoders and could be implemented in a generic fashion. In particular, it...

## Expected Behavior There are a variety of applications in which zero-indexing would be preferred for the OrdinalEncoder. One example is preparing features for a PyTorch model with categorical embeddings,...

CountEncoder tests in tests/test_encoders.py are skipped

## Expected Behavior `tests/test_encoders.py` should be running for all encoders. ## Actual Behavior CountEncoder is missing from `__all__` in` category_encoders/__init__.py`. This has the effect that tests are skipped. 11 of...

## Expected Behavior OneHotEncoder category_mapping should return `self.mapping` (that is calculated in fit() and generated by generate_mapping() ) ## Actual Behavior OneHotEncoder category_mapping returns self.ordinal_encoder.category_mapping. I think ordinal_encoder is an...
