tf.contrib.layers.layer_norm(*args, **kwargs)

Adds a Layer Normalization layer from https://arxiv.org/abs/1607.06450.

"Layer Normalization"

Jimmy Lei Ba, Jamie Ryan Kiros, Geoffrey E. Hinton

Can be used as a normalizer function for conv2d and fully_connected.

Args:

• inputs: a tensor with 2 or more dimensions. The normalization occurs over all but the first dimension.
• center: If True, subtract beta. If False, beta is ignored.
• scale: If True, multiply by gamma. If False, gamma is not used. When the next layer is linear (also e.g. nn.relu), this can be disabled since the scaling can be done by the next layer.
• activation_fn: activation function, default set to None to skip it and maintain a linear activation.
• reuse: whether or not the layer and its variables should be reused. To be able to reuse the layer scope must be given.
• variables_collections: optional collections for the variables.
• outputs_collections: collections to add the outputs.
• trainable: If True also add variables to the graph collection GraphKeys.TRAINABLE_VARIABLES (see tf.Variable).
• scope: Optional scope for variable_op_scope.

Returns:

A Tensor representing the output of the operation.

Raises:

• ValueError: if rank or last dimension of inputs is undefined.
