Community detection in spatial correlation graphs: Application to non-stationary ground motion modeling

Y Chen, JW Baker - Computers & Geosciences, 2021 - Elsevier
In this paper, we propose a community detection method to find regions in spatial data with
higher correlations. We construct a 'correlation deviation graph'that considers the influence …

Finding core-periphery structures with node influences

X Shen, S Aliko, Y Han, JI Skipper… - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
