Project Description


Python Machine Learning Toolkit


pymltk is a Python package helping data scientists with their daily work of (pre)processing data and building predictive or other machine learning models. It offers various Python functions which implement common operations done by data scientists during their daily work.

All functions of this package …

  • … do one thing and (try to) do it well.
  • … operate on pandas as well as dask dataframes.
  • … are fully tested and documented.
  • … offer a clean and consistent UI.

This package was inspired by mlr, a R package which offers similar functionality with respect to data (pre)processing (but in addition offers a lot more).

Function Overview

  • parse_columns: Parsing features with a specified dtype.
  • parse_missings: Parsing specified values as missing values.
  • merge_levels: Merging levels/values of a feature depending on several criteria.
  • impute_missings: Imputing missing values based on several strategies.
  • remove_constants: Removing features with no/low variability.


Currently only the development version in this repository is available. In the future, a stable release on pypi is planned.


A detailed documentation of each function provided by pymltk is available on
