Reinforcement learning

I have been looking into a machine learning technique called reinforcement learning (RL) lately. This was on my TODO for a while, and I must say, this field is incredibly exciting! I played around with some OpenAI Gym environments and re-implemented two RL algorithms mostly based on code I found from other authors.

After spending many hours on this, I can still only get my algorithm to solve the Cartpole problem, where the goal is to balance a pole on a moving cart (video below). I haven’t cracked the nut on a continuous action problem like Pendulum, where the goal is to swing the pendulum into an upright position and keep it there (video below).

Anyway, here is my implementation of the RL algorithms. Perhaps it will be useful for someone :-)
