In order to transfer the rules into a new policy π r , the KL divergence between the posterior of π and π r should be minimized, this can be formally defined as minKL(P π (A t |S t , θ π )||P πr (A t |S t , θ π )) (5) Optimizing the constrained convex problem defined by Eq.
here we use a rule pattern as the Fig.1 shows (?).
