Nettet24. feb. 2024 · An improved of the epsilon-greedy method is called a decayed-epsilon-greedy method. In this method, for example, we train a policy with totally N epochs/episodes (which depends on the problem specific), the algorithm initially sets = (e.g., =0.6), then gradually decreases to end at = (e.g., =0.1) over training … NettetProblem 2: Q-Learning [35 pts.] You are to implement the Q-learning algorithm. Use a discount factor of 0.9. We have simulated an MDP-based grid world for you. The interface to the simulator is to provide a state and action and receive a new state and receive the reward from that state.
