By going beyond the old edge-based … Witryna1 lip 2024 · The use of graph cut method can better determine whether to combine or to separate these trees, because it takes into account more global structural information …
Witryna28 kwi 2016 · Clustering methods are applied regularly in the bibliometric literature to identify research areas or scientific fields. These methods are for instance used to group publications into clusters based on their relations in a citation network. In the network science literature, many clustering methods, often referred to as graph partitioning … WitrynaAbstract. Local graph clustering methods aim to find a cluster of nodes by exploring a small region of the graph. These methods are attractive because they enable targeted clustering around a given seed node and are faster than traditional global graph clustering methods because their runtime does not depend on the size of the input …
WitrynaThe proposed stochastic model for graph generation seems interesting and novel. I find it interesting to see that the min-max graph partitioning problem can be almost recovered under certain conditions of the graph. ... Our work is the first to provide analytic guarantees for streaming hypergraph partitioning. We hope that it will spark further ...
