WebSpecifically, we'll use Python to implement the Q-learning algorithm to train an agent to play OpenAI Gym's Frozen Lake game that we introduced in the previous video. Let's get to it! Learning how to play Frozen Lake is like learning which action you should choose in every state. To know which action is the best in a given state, we would like to assign a quality value to our actions. We have 16 states and 4 actions, so want to calculate 16 x 4 = 64 values. plotly dash julia
