WebNov 28, 2024 · Recently, Deep Deterministic Policy Gradient (DDPG) is a popular deep reinforcement learning algorithms applied to continuous control problems like autonomous driving and robotics. Although DDPG can produce very good results, it has its drawbacks. DDPG can become unstable and heavily dependent on searching the correct … WebInterestingly, DDPG can sometimes find policies that exceed the performance of the planner, in some cases even when learning from pixels (the planner always plans over the underlying low-dimensional state space). 2 BACKGROUND We consider a standard reinforcement learning setup consisting of an agent interacting with an en-
