The gradient operator for the SparseAdd op.
tf.raw_ops.SparseAddGrad(
backprop_val_grad, a_indices, b_indices, sum_indices, name=None
)
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.
