SparseAddGrad

public final class SparseAddGrad

The gradient operator for the SparseAdd op.

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.

Constants

String

OP_NAME

The name of this op, as known by TensorFlow core engine
