tensorflow::ops::FusedBatchNormGradV2

#include <nn_ops.h>

Gradient for batch normalization.

Summary

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.

Arguments:

  • scope: A Scope object
  • y_backprop: 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.
  • reserve_space_1: 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: 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.

Optional attributes (see Attrs):

  • epsilon: A small float number added to the variance of x.
  • data_format: The data format for y_backprop, x, x_backprop. Either "NHWC" (default) or "NCHW".
  • is_training: A bool value to indicate the operation is for training (default) or inference.

Returns:

  • Output x_backprop: A 4D Tensor for the gradient with respect to x.
  • Output scale_backprop: A 1D Tensor for the gradient with respect to scale.
  • Output offset_backprop: A 1D Tensor for the gradient with respect to offset.
  • Output reserve_space_3: Unused placeholder to match the mean input in FusedBatchNorm.
  • Output reserve_space_4: Unused placeholder to match the variance input in FusedBatchNorm.
