WebAug 21, 2016 · DDPG is an actor-critic algorithm as well; it primarily uses two neural networks, one for the actor and one for the critic. These networks compute action predictions for the current state and generate a temporal … WebIn order to scale Q-learning they intro-duced two major changes: the use of a replay buffer, and a separate target network for calculating y t. We employ these in the context of DDPG and explain their implementation in the next section. 3 ALGORITHM It is not possible to straightforwardly apply Q-learning to continuous action spaces, because in con-

But the problem didn't converges, so I increased the number of neurons per hidden layer (300-400) and decreased the learning rate to about 0.0001.
WebAug 21, 2016 · Google DeepMind has devised a solid algorithm for tackling the continuous action space problem. Building off the prior work of on Deterministic Policy Gradients, they have produced a policy-gradient actor-critic algorithm called Deep Deterministic Policy Gradients (DDPG) that is off-policy and model-free, and that uses some of the deep … WebUnder high traffic intensities (100% and 75%), the reward curve is the best when the actor learning rate is 0.0001, as shown in Figure 3a,b. The reward curve is the best when the actor learning rate is 0.1 at low traffic intensities (50% and 25%), as shown in Figure 3c,d.
