tensorflow:: ops:: 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.
