dirty_cat is a Python module for machine-learning on dirty categorical variables.
Website: https://dirty-cat.github.io/
dirty_cat's SuperVectorizer automatically turns pandas data frames into numerical arrays suitable for learning.
For a detailed description of the problem of encoding dirty categorical data, see Similarity encoding for learning with dirty categorical variables [1] and Encoding high-cardinality string categorical variables [2].
dirty_cat requires:
- Python (>= 3.8)
- NumPy (>= 1.17.3)
- SciPy (>= 1.4.0)
- scikit-learn (>= 0.23.0)
- pandas (>= 1.2.0)
If you already have a working installation of NumPy and SciPy,
the easiest way to install dirty_cat is using pip
pip install -U --user dirty_cat
