WebThe original implementation of DDPG by Lillicrap et al. (2016) used batch normalization. However, it has not been widely used in DDPG implementations as direct application of batch normalization to off-policy learning is problematic. While training the critic, the action-value function is evaluated two times (Q(s;a) and Q(s0;ˇ(s0))).

Why does the RL Toolbox not support BatchNormalization layer?

WebBecause the Batch Normalization is done over the C dimension, computing statistics on (N, L) slices, it’s common terminology to call this Temporal Batch Normalization. Parameters: num_features ( int) – number of features or channels C C of the input eps ( float) – a value added to the denominator for numerical stability. Default: 1e-5 WebDDPG makes use of the same ideas along with batch normalization. DDPG, or Deep Deterministic Policy Gradient, is an actor-critic, model-free algorithm based on the deterministic policy gradient that can operate over continuous action spaces.
