... of J ( u ) processed using the central difference method, such that the deri- vative for any point of index u ∉ {1, N s } is processed as ∇ (J (u)) = 1 2 ( J (u +1)− J (u − 1)) . For the first point, we use the forward ... where its slope is positive for signal plus noise samples and negative for noise samples. • For 1 ≤ u ≤ m 1 : J ( u ) decreases only if ∂E[J (u)] ∂u < 0 , an...

For instance, Mochizuki performed theoretical analysis ... that our proposed algorithms are much faster for scale-free networks than for random networks. However, we could not yet perform theoretical analysis for scale-free networks. Thus...
