tf.raw_ops.SparseAddGrad
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.
| Args | |
|---|---|
backprop_val_grad |
A Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, complex64, int64, qint8, quint8, qint32, bfloat16, uint16, complex128, half, uint32, uint64. 1-D with shape [nnz(sum)]. The gradient with respect to the non-empty values of the sum. |
a_indices |
A Tensor of type int64. 2-D. The indices of the SparseTensor A, size [nnz(A), ndims]. |
b_indices |
A Tensor of type int64. 2-D. The indices of the SparseTensor B, size [nnz(B), ndims]. |
sum_indices |
A Tensor of type int64. 2-D. The indices of the sum SparseTensor, size [nnz(sum), ndims]. |
name |
A name for the operation (optional). |
| Returns | |
|---|---|
A tuple of Tensor objects (a_val_grad, b_val_grad). |
|
a_val_grad |
A Tensor. Has the same type as backprop_val_grad. |
b_val_grad |
A Tensor. Has the same type as backprop_val_grad. |
