Reinforcement Learning Explained Visually Part 6 Policy Gradients Hence, if we replace r(τ) by the discounted return g t , we arrive at the classic algorithm policy gradient algorithm called reinforce. this doesn’t totally alleviate the problem as we discuss further. reinforce (and baseline) to reiterate, the reinforce algorithm computes the policy gradient as. reinforce gradient. This paper introduces a policy gradient approach to reinforcement learning with function approximation, in which the policy is represented by its own function approximator and updated by the gradient of expected reward. it proves the convergence of a version of policy iteration and provides an unbiased estimate of the gradient using an approximate value function.
