Simple and easy-to-understand ml algorithm implementations

ml-playground

This project reuses code and is highly inspired by (selected) great resources:

1. MLAlgorithms
2. reinforcement-learning.

It's good to learn machine learning by implementing algorithms, and better if we can write them in an elegant and readable way. Then we can review later or others might easily learn from them.

So I manage to use succinct codes with demo example to illustrate the essence of ml algorithms.
