Experience
Reinforcement Learning for Atari Breakout (TensorFlow)
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.
