Gradient for batch normalization.
tf.raw_ops.FusedBatchNormGradV2( y_backprop, x, scale, reserve_space_1, reserve_space_2, 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. |
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). |
Returns | |
---|---|

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_3 | A Tensor . Has the same type as reserve_space_1 . |
reserve_space_4 | A Tensor . Has the same type as reserve_space_1 . |
