WebOct 4, 2024 · Our Frozen-Lake environment will be a 4x4 grid consisting of frozen squares and squares with holes, a total of 16 squares. Each square represents a possible state, which we can label by assigning numbers to them. Frozen-Lake game state space with numbers assigned to each state. Image by author. WebQ-Learning is the algorithm we use to train our Q-Function, an action-value function that determines the value of being at a particular state and taking a specific action at that state. Given a state and action, our Q Function outputs a state-action value (also called Q-value) The Q comes from "the Quality" of that action at that state. goldcrest homes sandy utah
