WebDec 8, 2016 · In reinforcement learning, the Monte Carlo method is used to derive Q-values after repeatedly seeing the same state-action pair. It sets the Q-value, Q(s,a), as the average reward after many visits to the same state-action pair (s, a). This method removes the need for using a learning rate or a discount rate.

WebThe procedural form of the algorithm is: The parameters used in the Q-value update process are: - the learning rate, set between 0 and 1. Setting it to 0 means that the Q-values are … After steps into the future the agent will decide some next step. The weight for this step is calculated as , where (the discount factor) is a number between 0 and 1 () and has the effect of valuing rewards received earlier higher than those received later (reflecting the value of a "good start"). may also be interpreted as the probability to succeed (or survive) at every step .
