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.
|
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" . 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).
|
