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). |
