This python based RL experiment plays a Py Pong Game (DQN control of Left Hand Yellow Paddle against a programmed RHS Paddle) The Objective is simply measured as successfully returning of the Ball by the Yellow RL DQN Agent. The Environment for the game is a two dimensional space with a ball . Starts with S0. The post gives a nice, illustrated overview of the most fundamental RL algorithm: Q-learning. Therefore, after learning the optimal stopping policy, it is essential to do a full-blown Monte Carlo to find the actual price as below. The development of Q-learning ( Watkins & Dayan, 1992) is a big breakout in the early days of Reinforcement Learning. An earlier version was titled "Striving for Simplicity in Off-Policy Deep Reinforcement Learning" and presented as a contributed talk at NeurIPS 2019 Deep RL Workshop. With reinforcement learning and policy gradients, the assumptions usually mean the episodic setting where an agent engages in multiple trajectories in its environment.
