WebMay 16, 2024 · In DDPG, the critic loss is the temporal difference (as in classique deep Q learning): critic_loss = (R - gamma*Q(t+1) - Q(t))**2 Then the critic’s gradient is obtained by a simple backward of this loss. For the actor gradient, things are more complex: it’s an estimation of the policy gradient, given by: actor_grad = Q_grad * mu_grad
