Hi everyone,

I am developing an open-source library to facilitate building local hierarchical classifiers in Python. The library, named HiClass ([https://arxiv.org/abs/2112.06560](https://arxiv.org/abs/2112.06560)), is compatible with scikit-learn's API.

Hierarchies occur naturally in many problems, but often are not explored when building classifiers. However, exploiting the hierarchical information in the data usually improves predictive performance. For example, in the table below there is a comparison between the local hierarchical classifiers implemented in HiClass and Microsoft's LightGBM on a consumer complaints dataset, where we …
