Abstract Let G be a graph with vertex set V(G) = {v1, v2, …, vn} and edge set E(G). For any vertex vi ∈ V(G), let di denote the degree of vi. The normalized Laplacian matrix of the graph G is the ...

Plot them so that the i-th smallest eigenvalue ?i, 1 ? i ? n, is drawn at (x, y) with x = (i - 1)/(n - 1) and y = ?i.

Spectral clustering is quite complex, but it can reveal patterns in data that aren't revealed by other clustering techniques. Data clustering is the process of grouping data items so that similar ...
