feng - feature engineering for machine-learning champions\n\n[![Build Status](https://travis-ci.org/mewwts/feng.svg?branch=master)](https://travis-ci.org/mewwts/feng)\n\n\nfeng is a Python module for smoothly engineering features from your Pandas DataFrame so that you can win that Kaggle competition.\n\n### Why feng?\n\u003e *We spent most of our efforts in feature engineering.*\n\u003e \n\u003e -- Xavier Cohort, [after winning one of many Kaggle competitions](http://blog.kaggle.com/2013/04/10/qa-with-xavier-conort/)\n\nfeng helps data scientists in what is arguably the most critical part of a machine-learning pipeline: [feature engineering](https://en.wikipedia.org/wiki/Feature_engineering). \n\nIt's built for fans of [Pandas](http://pandas.pydata.org/) and makes use of [scikit-learn](http://scikit-learn.org/) pipelines and transformers.\n\n\u003e *... some machine learning projects succeed and some fail. What makes the difference? Easily the most important factor is the features used.*\n\u003e\n\u003e -- Pedro Domingos, [A Few Useful Things to Know about Machine Learning](http://homes.cs.washington.edu/~pedrod/papers/cacm12.pdf)\n\n\nMade with ♥️ in Barcelona.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmewwts%2Ffeng","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmewwts%2Ffeng","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmewwts%2Ffeng/lists"}
