Layer normalization layer (Ba et al., 2016).
Normalize the activations of the previous layer for each given example in a batch independently, rather than across a batch like Batch Normalization. i.e. applies a transformation that maintains the mean activation within each example close to 0 and the activation standard deviation close to 1.
axis: Integer or List/Tuple. The axis that should be normalized (typically the features axis).
epsilon: Small float added to variance to avoid dividing by zero.
center: If True, add offset of
betato normalized tensor. If False,
scale: If True, multiply by
gamma. If False,
gammais not used. When the next layer is linear (also e.g.
nn.relu), this can be disabled since the scaling will be done by the next layer.
beta_initializer: Initializer for the beta weight.
gamma_initializer: Initializer for the gamma weight.
beta_regularizer: Optional regularizer for the beta weight.
gamma_regularizer: Optional regularizer for the gamma weight.
beta_constraint: Optional constraint for the beta weight.
gamma_constraint: Optional constraint for the gamma weight.
trainable: Boolean, if
Truethe variables will be marked as trainable.
Arbitrary. Use the keyword argument
(tuple of integers, does not include the samples axis)
when using this layer as the first layer in a model.
Same shape as input.
