According to the recently presented generalized extensivity test [M. Nooijen, K.R. Shamasundar, D. Mukherjee, Mol. Phys. 103 (2005) 2277] the concepts of and relations between connectivity, separability, and co
Sign In Paper Minimum Spectral Connectivity Projection Pursuit We study the problem of determining the optimal low dimensional projection for maximising the separability of a binary partition of an unlabelled dataset, as measured by spectral graph theory. This is achieved by finding projections which ...
Graph theory has become an important and widely used approach to summarize brain function (Sporns, 2011). In addition, concepts such as “small-worldness” and “rich club networks” have already been studied extensively in the context of schizophrenia (Bullmore and Sporns, 2009, Zalesky et ...
Eigenvalues and eigenfunctionsWe study the problem of determining the optimal univariate subspace for maximising the separability of a binary partition of unlabeled data, as measured by spectral graph theory. This is achieved by ?nding projections which minimise the second eigenvalue of the Laplacian ...

The z-scores of ADI-R (social, verbal, and repetitive stereotypes) were used to identify potential ASD subgroups, and to assess the separability of the clusters. Before clustering, the optimal cluster number and the validity of the cluster solution were determined with the ‘Nbclust’ package i...
Using realistic simulations, we show here that bundling yields hyperedges with good separability of true positives and little loss in the true positive rate. Hyperedge bundling thus significantly decreases graph noise by minimizing the false-positive to true-positive ratio. Finally, we demonstrate the...
A KS value nearing 1 signifies a high level of distinguishability for the connectivity between two channels, whereas a value approaching 0 suggests a low level of separability. Here, the two-sample KS test compares the underlying distributions of two independent samples regarding the MI classes. -...
To compare functional connectivity between the groups mentioned above, first, we have to check which connections are relevant for class separability. It is worth noting that a high correlation in the functional connectivity matrix does not guarantee a higher class separability. Therefore, we use the...
