  • Cartpole is a simple, classic reinforcement learning problem - it's a good environment to use for debugging. From experience with DQN and Cartpole I expected to see a inflation in the Q values.
  • Like DQN, it can be used on any environment with a discrete action space. The main difference between C51 and DQN is that rather than simply predicting the Q-value for each state-action pair, C51 predicts a histogram model for the probability distribution of the Q-value: DA: 61 PA: 46 MOZ Rank: 75.

  • Cartpole is an environment from the OpenAI gym — a library that allows you to use small and simple environments to see if your agents are learning. In Cartpole, you control the cart (by pushing it left or right), and the goal is for the pole to stay in equilibrium. For any given situation, your agent must be able to know what to do.

  • In this example, we will save batches of experiences generated during online training to disk, and then leverage this saved data to train a policy offline using DQN. First, we run a simple policy gradient algorithm for 100k steps with "output": "/tmp/cartpole-out" to tell RLlib to write simulation outputs to the /tmp/cartpole-out directory.

The system is controlled by applying a force of +1 or -1 to the cart. The pendulum starts upright, and the goal is to prevent it from falling over. A reward of +1 is provided for every timestep that the pole remains upright.
