finch is a project that contains the collection of my implementations on machine learning models and their tests based on modern frameworks (mainly TensorFlow and PyTorch).

I am actively responsible for this project, and there will be more models in the future ...

You are more than welcome to send an email to me in English / Chinese for any suggestion or question, I will try my best to answer as soon as I see it.

Installation

First get the project folder

git clone https://github.com/zhedongzheng/finch.git

Then run the test file that you are interested in

python xxxx_test.py

The main dependence is:

• TensorFlow >=1.2
• PyTorch >=0.12
• scikit-learn

Style of My Code

I write each model as a single Class with fit() and predict() methods (scikit-learn API style), and then write separate test files for different incoming data. All the code below follow this style.
