relu

ray.rllib.utils.numpy.relu(x: ndarray, alpha: float = 0.0) → ndarray

Implementation of the leaky ReLU function.

y = x * alpha if x < 0 else x

Parameters:

• x (ndarray) – The input values.

• alpha (float) – A scaling (“leak”) factor to use for negative x.

Returns:

The leaky ReLU output for x.

Return type:

ndarray
