L'operatore gradiente per SparseAdd op.
L'operazione SparseAdd calcola A + B, dove A, B e la somma sono tutti rappresentati come oggetti "SparseTensor". Questa operazione accetta il gradiente a monte rispetto ai valori non vuoti della somma e restituisce i gradienti rispetto ai valori non vuoti di A e B.
