First, an adjacency matrix was constructed by measuring the Euclidean distance of the time- and frequency-domain characteristics of small samples to achieve the pre-classification of nodes.

Web2) = 2 regardless of the choice of weight matrix. However, setting G = K 3 the situation becomes more complicated as we can force λW n−1 to be diﬀerent values in [3/2,2] with a proper choice of weight matrix. The upper bound on λW n−1 is not interesting because any graph may obtain it by having only one non-zero edge weight.

For an undirected graph, the adjacency matrix is symmetric: the row ii, column jj entry is 1 if and only if the row jj, column ii entry is 1. For a directed graph, the adjacency matrix need not be symmetric.
