This repo originally intended to host my answers to the exercies for the book by Sutton & Barton, Reinforcement Learning: An Introduction
A free pdf can be found here
But now it has become more like a place for my own notes on anything related to ML/stats.
Note: if you find the formatting some notebooks (esp. with many equations) doesn't look good on github,, try visualize them on http://nbviewer.jupyter.org/github/zyxue/sutton-barto-rl-exercises/tree/master/.
