Reinforcement Learning for Atari Breakout (TensorFlow)

I applied deep reinforcement learning techniques to design a convolutional neural network (CNN) based AI that could learn to play the classic game Atari Breakout using only screen images and the current score.

This algorithm was modeled after the A3C and Deep-Q CNN formula described in the famous DeepMind papers (Mnih et al, 2013, 2016). I also added enhancements such as e-greedy action selection, experience replay, and frame stacking to improve its learning curve.

In the end, the AI was able to achieve a super-human score of 220 after a full day of training, compared to the average human score of 32.
