Figure 3From: PLW: Probabilistic Local Walks for detecting protein complexes from protein interaction networksExample network to illustrate probabilistic local walks. Edge labels show the common neighbour similarity of the two vertices. The random walker's next step is determined by a weighted random choice, e.g., at vertex 1, the probability of travelling to vertex 2 is 0 . 89 0 . 89 + 0 . 89 + 0 . 89 = 1 3 .Back to article page
