p>Input shape Arbitrary. Use the keyword argument `input_shape` (list of integers,
does not include the samples axis) when using this layer as the first layer in a model.
This layer, as of now, works on a 4-D tensor where the tensor should have the
shape [N X H X W X C] TODO: Add support for NCHW data format and FC layers. Output shape
Same shape as input. References - [Filter Response Normalization Layer: Eliminating Batch
