Note that the size of 4D Tensors are defined by either "NHWC" or "NCHW".
The size of 1D Tensors matches the dimension C of the 4D Tensors.
Args
y_backprop
A Tensor. Must be one of the following types: half, bfloat16, float32.
A 4D Tensor for the gradient with respect to y.
x
A Tensor. Must have the same type as y_backprop.
A 4D Tensor for input data.
scale
A Tensor of type float32.
A 1D Tensor for scaling factor, to scale the normalized x.
reserve_space_1
A Tensor. Must be one of the following types: float32.
When is_training is True, a 1D Tensor for the computed batch
mean to be reused in gradient computation. When is_training is
False, a 1D Tensor for the population mean to be reused in both
1st and 2nd order gradient computation.
reserve_space_2
A Tensor. Must have the same type as reserve_space_1.
When is_training is True, a 1D Tensor for the computed batch
variance (inverted variance in the cuDNN case) to be reused in
gradient computation. When is_training is False, a 1D Tensor
for the population variance to be reused in both 1st and 2nd
order gradient computation.
reserve_space_3
A Tensor. Must have the same type as reserve_space_1.
When is_training is True, a 1D Tensor for some intermediate results to be reused
in gradient computation. When is_training is False, a dummy empty Tensor will be
created.
epsilon
An optional float. Defaults to 0.0001.
A small float number added to the variance of x.
data_format
An optional string from: "NHWC", "NCHW", "NDHWC", "NCDHW". Defaults to "NHWC".
The data format for y_backprop, x, x_backprop.
Either "NHWC" (default) or "NCHW".
is_training
An optional bool. Defaults to True.
A bool value to indicate the operation is for training (default)
or inference.
name
A name for the operation (optional).
Returns
A tuple of Tensor objects (x_backprop, scale_backprop, offset_backprop, reserve_space_4, reserve_space_5).
