SparseFillEmptyRows'un gradyanı.
'[N]' şeklinde ters_index_map vektörlerini ve 'N_full >= N' olan '[N_full]' şeklinde grad_values vektörlerini alır ve verileri 'd_values' ya da 'd_default_value'ya kopyalar. Burada 'd_values', '[N]' şeklindedir ve 'd_default_value' bir skalerdir.
d_values[j] = grad_values[reverse_index_map[j]] d_default_value = toplam_{k : 0 .. N_full - 1} ( grad_values[k] * 1{k, ters_index_map'te değil})
