Parameter-exploring policy gradients
WebOct 29, 2024 · In this 1992 paper, Williams outlined an approach to estimate the gradient of the expected rewards with respect to the model parameters of a policy neural network. This paper also proposed using REINFORCE as an Evolution Strategy, in Section 6 of the paper. WebWe also show that the improvement is largest when the parameter samples are drawn symmetrically. Lastly we analyse the importance of the individual components of our method by incrementally incorporating them into the other algorithms, and measuring the gain in performance after each step.

WebFeb 19, 2024 · Policy Policy, as the agent’s behavior function π, tells us which action to take in state s. It is a mapping from state s to action a and can be either deterministic or stochastic: Deterministic: π ( s) = a. Stochastic: π ( a s) = P π [ A = a S = s]. Value Function WebJul 14, 2024 · Taken from Sutton & Barto, 2024 REINFORCE algorithm. Now with the policy gradient theorem, we can come up with a naive algorithm that makes use of gradient ascent to update our policy parameters.
