tensorflow::ops::FusedBatchNormGradV3
#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.
Args:
- 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.
- reserve_space_3: 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.
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:
