Home Credit Default Risk: Open Solution

Join the chat at https://gitter.im/minerva-ml/open-solution-home-credit license

This is an open solution to the Home Credit Default Risk challenge 🏡.

Our goals

We are building entirely open solution to this competition. Specifically:

  1. Learning from the process - updates about new ideas, code and experiments is the best way to learn data science. Our activity is especially useful for people who wants to enter the competition, but lack appropriate experience.
  2. Encourage more Kagglers to start working on this competition.
  3. Deliver open source solution with no strings attached. Code is available on our GitHub repository 💻. This solution should establish solid benchmark, as well as provide good base for your custom ideas and experiments. We care about clean code 😃
  4. We are opening our experiments as well: everybody can have live preview on our experiments, parameters, code, etc. Check: Home Credit Default Risk 📈 and screens below.

Disclaimer

In this open source solution you will find references to the neptune.ml. It is free platform for community Users, which we use daily to keep track of our experiments. Please note that using neptune.ml is not necessary to proceed with this solution. You may run it as plain Python script 🐍.

How to start?

Start experimenting with ready-to-use code

You can jump start your participation in the competition by using our starter pack. Installation instruction below will guide you through the setup.

Installation (fast track)

  1. Clone repository and install requirements (use Python3.5)
  2. Register to the neptune.ml (if you wish to use it)
  3. Run experiment based on LightGBM:

🔱

neptune account login
neptune run --config configs/neptune.yaml main.py train_evaluate_predict_cv --pipeline_name lightGBM

🐍

python main.py -- train_evaluate_predict_cv --pipeline_name lightGBM
