Batch normalization.
tf.raw_ops.FusedBatchNormV2( x, scale, offset, mean, variance, epsilon=0.0001, exponential_avg_factor=1, 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 | |
---|---|
x | A Tensor . Must be one of the following types: half , bfloat16 , float32 . A 4D Tensor for input data. |
scale | A Tensor . Must be one of the following types: float32 . A 1D Tensor for scaling factor, to scale the normalized x. |
offset | A Tensor . Must have the same type as scale . A 1D Tensor for offset, to shift to the normalized x. |
mean | A Tensor . Must have the same type as scale . A 1D Tensor for population mean. Used for inference only; must be empty for training. |
variance | A Tensor . Must have the same type as scale . A 1D Tensor for population variance. Used for inference only; must be empty for training. |
epsilon | An optional float . Defaults to 0.0001 . A small float number added to the variance of x. |
exponential_avg_factor | An optional float . Defaults to 1 . |
data_format | An optional string from: "NHWC", "NCHW" . Defaults to "NHWC" . The data format for x and y. 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 (y, batch_mean, batch_variance, reserve_space_1, reserve_space_2). | |
y | A Tensor . Has the same type as x . |
batch_mean | A Tensor . Has the same type as scale . |
batch_variance | A Tensor . Has the same type as scale . |
reserve_space_1 | A Tensor . Has the same type as scale . |
reserve_space_2 | A Tensor . Has the same type as scale . |
