Webb5 maj 2024 · A two-step random walk algorithm (Two- RWR) is proposed to identify cancer genes based on various biological data using a heterogeneous network constructed by protein-protein interaction network (PPI), pathway, miRNA similarity and disease similarity network to identify potential cancer genes. 2. Highly Influenced. WebbRandom walk with restarts (RWR) samples the graph by taking random walks from a set of start nodes (see the startNodes parameter below). On each step of a random walk, there is some probability (see the restartProbability parameter below) that the walk stops, and a new walk from one of the start nodes starts instead (i.e. the walk restarts).
