Finding community structure using the ordered random graph model
Masaki Ochi, Tatsuro Kawamoto
Visualization of the adjacency matrix enables us to capture macroscopic features of a network when the matrix elements are aligned properly. Community structure, a network consisti…
Consistency between ordering and clustering methods for graphs
Tatsuro Kawamoto, Masaki Ochi, Teruyoshi Kobayashi
A relational dataset is often analyzed by optimally assigning a label to each element through clustering or ordering. While similar characterizations of a dataset would be achieved…
Single-trajectory map equation
Tatsuro Kawamoto
Community detection, the process of identifying module structures in complex systems represented on networks, is an effective tool in various fields of science. The map equation, w…
Contribution of directedness in graph spectra
Masaki Ochi, Tatsuro Kawamoto
In graph analyses, directed edges are often approximated to undirected ones so that the adjacency matrices may be symmetric. However, such simplification has not been thoroughly ve…
