SparseFillEmptyRowsGrad

Il gradiente di SparseFillEmptyRows.
Prende i vettori reverse_index_map, a forma di "[N]" e grad_values, a forma di "[N_full]", dove "N_full >= N" e copia i dati in "d_values" o "d_default_value". Qui "d_values" ha la forma "[N]" e "d_default_value" è uno scalare.
d_values[j] = grad_values[reverse_index_map[j]] d_default_value = sum_{k : 0 .. N_full - 1} ( grad_values[k] * 1{k non in reverse_index_map})
