Nettet13. sep. 2016 · The concept of random walks can be traced back to 1905 when Karl Pearson derived a model to describe the infection dynamics of mosquitoes in a forest [1, 2].Simultaneously, this same year Albert Einstein published his work on Brownian motion—the random motion of particles suspended in a fluid—which he modeled as … Nettet15. jun. 2024 · Background: The misregulation of microRNA (miRNA) has been shown to cause diseases. Recently, we have proposed a computational method based on a random walk framework on a miRNA-target gene network to predict disease-associated miRNAs. The prediction performance of our method is better than that of some existing state-of …

NettetA random walk can be thought of as a random process in which a token or a marker is randomly moved around some space, that is, a space with a metric used to compute distance.
