Introduction to Making a Simple Game AI with Deep Reinforcement Learning

Minimal and Simple Deep Q Learning Implemenation in Keras and Gym. Under 100 lines of code!

The explanation for the dqn.py code is covered in the blog article https://keon.io/deep-q-learning/

I made minor tweaks to this repository such as load and save functions for convenience.

I also made the memory a deque instead of just a list. This is in order to limit the maximum number of elements in the memory.

The training might be unstable for dqn.py. This problem is mitigated in ddqn.py. I'll cover ddqn in the next article.
