Gradient op for MirrorPad
op. This op folds a mirror-padded tensor.
tf.raw_ops.MirrorPadGrad(
input, paddings, mode, name=None
)
This operation folds the padded areas of input
by MirrorPad
according to the
paddings
you specify. paddings
must be the same as paddings
argument
given to the corresponding MirrorPad
op.
The folded size of each dimension D of the output is:
input.dim_size(D) - paddings(D, 0) - paddings(D, 1)
For example:
# 't' is [[1, 2, 3], [4, 5, 6], [7, 8, 9]].
# 'paddings' is [[0, 1]], [0, 1]].
# 'mode' is SYMMETRIC.
# rank of 't' is 2.
pad(t, paddings) ==> [[ 1, 5]
[11, 28]]
