public final class
FusedBatchNormGradV3
Gradient for batch normalization.
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.

Public Methods

Factory method to create a class wrapping a new FusedBatchNormGradV3 operation.
Parameters
scope | current scope |
---|---|
yBackprop | A 4D Tensor for the gradient with respect to y. |
x | A 4D Tensor for input data. |
scale | A 1D Tensor for scaling factor, to scale the normalized x. |
reserveSpace1 | 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. |
reserveSpace2 | 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. |
reserveSpace3 | 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. |
