Centralitymetrics such as betweenness and closeness have been used to identify important nodes in a network. However, it takes days to months on a high-end workstation to compute the centrality of today’s networks. Themain reasons are the size and the irregular structure of these networks.While today’s computing units excel at processing dense and regular data, their performance is questionable when the data is sparse. In this work, we show how centrality computations can be regularized to… CONTINUE READING
