Covariate-assisted spectral clustering
WebFor most simulated conditions, covariate assisted spectral clustering yields superior results rela-tive to both regularized spectral clustering without node covariates and an … WebNov 9, 2024 · Affinity matrix construction is a key step in the spectral clustering. However, traditional spectral clustering methods usually ignore the intersection problem that may exist between the different clusters of data, so the resulting matrix could be unreliable. This paper proposes a new local covariance-based method to solve the above problem. …
