ELU层
ELU class
tf_keras.layers.ELU(alpha=1.0, **kwargs)
Exponential Linear Unit.
It follows:
f(x) = alpha * (exp(x) - 1.) for x < 0
f(x) = x for x >= 0
Input shape
Arbitrary. Use the keyword argument input_shape
(tuple of integers, does not include the samples axis)
when using this layer as the first layer in a model.
Output shape
Same shape as the input.
Arguments
- alpha: Scale for the negative factor.
