Vanilla policy gradient

In the vanilla policy gradient approach, the aim would be to update the policy using the policy gradient estimate with better baseline estimation.

Following is the pseudo code to implement the vanilla policy gradient to find the optimal policy:

Initialize: Policy parameter , and baseline bfor iteration = 1,2,......N   do        Collect a set of trajectories using the current policy        At each time step t in each trajectory, compute the following:            returns ,and            advantage estimate         Refit the baseline function                 end for
