L'opérateur de dégradé pour l'opération SparseAdd.
L'opération SparseAdd calcule A + B, où A, B et la somme sont tous représentés sous forme d'objets « SparseTensor ». Cette opération prend en compte le gradient en amont par rapport aux valeurs non vides de la somme et génère les gradients par rapport aux valeurs non vides de A et B.
