tf.raw_ops.FusedBatchNormGradV3
Gradient for batch normalization.
tf.raw_ops.FusedBatchNormGradV3(
y_backprop, x, scale, reserve_space_1, reserve_space_2, reserve_space_3,
epsilon=0.0001, data_format='NHWC', is_training=True, name=None
)
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). | |
x_backprop | A Tensor. Has the same type as y_backprop. |
scale_backprop | A Tensor. Has the same type as reserve_space_1. |
offset_backprop | A Tensor. Has the same type as reserve_space_1. |
reserve_space_4 | A Tensor. Has the same type as reserve_space_1. |
reserve_space_5 | A Tensor. Has the same type as reserve_space_1. |
