skrub (formerly dirty_cat) is a Python library that facilitates prepping your tables for machine learning.
If you like the package, spread the word and ⭐ this repository!
skrub provides data assembling tools (TableVectorizer, fuzzy_join...) and encoders (GapEncoder, MinHashEncoder...) for morphological similarities, for which we usually identify three common cases: similarities, typos and variations
See our examples.
Semantic similarities are currently not supported. For example, the similarity between car and automobile is outside the reach of the methods implemented here.
This kind of problem is tackled by Natural Language Processing methods.
skrub can still help with handling typos and variations in this kind of setting.
For a detailed description of the problem of encoding dirty categorical data, see Similarity encoding for learning with dirty categorical variables1 and Encoding high-cardinality string categorical variables2.
The easiest way to install skrub is via `pip`:
pip install skrub -Uor `conda`:
conda install -c conda-forge skrubThe documentation includes more detailed installation instructions.
Dependencies and minimal versions are listed in the setup file.
Are listed on the skrub's website
