I designed this Challenge for you and me: Learn Deep Reinforcement Learning in depth in 60 days!!

You heard about the amazing results achieved by Deepmind with AlphaGo Zero and by OpenAI in Dota 2! Don't you want to know how they work? This is the right opportunity for you and me to finally learn Deep RL and use it on new exciting projects.

The ultimate aim is to use these general-purpose technologies and apply them to all sorts of important real world problems. Demis Hassabis

This repository wants to guide you through the Deep Reinforcement Learning algorithms, from the most basic ones to the highly advanced AlphaGo Zero. You will find the main topics organized by week and the resources suggested to learn them. Also, every week I will provide practical examples implemented in python to help you better digest the theory. You are highly encouraged to modify and play with them!

This is my first project of this kind, so please, if you have any idea, suggestion or improvement contact me at andrea.lonza@gmail.com.

During the whole challenge, I will update continuously this repository.. so stay tuned! #60DaysRLChallenge

Those who cannot rember the part are condomned to repeat it - George Santayana

This week, we will learn about the basic blocks of reinforcement learning, starting from the definition of the problem all the way through the estimation and optimization of the functions that are used to express the quality of a policy or state.

Project of the Week

Q-learning applied to FrozenLake. For exercise, you can solve the game using SARSA or implement Q-learning by yourself. In the former case, only few changes are needed.
