SparseAddGrad
#include <sparse_ops.h>
The gradient operator for the
SparseAdd
op.
Summary
The
SparseAdd
op calculates A + B, where A, B, and the sum are all represented as
SparseTensor
objects. This op takes in the upstream gradient w.r.t. non-empty values of the sum, and outputs the gradients w.r.t. the non-empty values of A and B.
Args:
-
scope: A
Scope
object
-
backprop_val_grad: 1-D with shape
[nnz(sum)]
. The gradient with respect to the non-empty values of the sum.
-
a_indices: 2-D. The
indices
of the
SparseTensor
A, size
[nnz(A), ndims]
.
-
b_indices: 2-D. The
indices
of the
SparseTensor
B, size
[nnz(B), ndims]
.
-
sum_indices: 2-D. The
indices
of the sum
SparseTensor
, size
[nnz(sum), ndims]
.
Returns:
-
Output
a_val_grad: 1-D with shape
[nnz(A)]
. The gradient with respect to the non-empty values of A.
-
Output
b_val_grad: 1-D with shape
[nnz(B)]
. The gradient with respect to the non-empty values of B.
