WebIn both cases, covariate assisted spectral clustering yields clusters that are easier to interpret neurologically. A low rank update algorithm is developed to reduce the computational cost of determining the tuning parameter for covariate assisted spectral clustering. As simulations demonstrate, the low rank update algorithm increases the … WebMar 19, 2024 · More generally, covariate-assisted spectral clustering can be used to find highly connected communities with relatively homogeneous covariates, where the balance between these two objectives is controlled by the tuning parameter and can be set …

WebJul 30, 2024 · Based on CA-DCSBM, we design the adjusted neighbor-covariate (ANC) data matrix, which leverages covariate information to assist community detection. We then prove that the spectral clustering method on the ANC matrix will combine the network and covariates. The resulting method, named CA-SCORE, is shown to have the oracle … WebNov 9, 2024 · Affinity matrix construction is a key step in the spectral clustering.
