Consider the un-directed graph shown in the Fig. The values inside the node refer to the feature value of the node. The order of the nodes is A,B,C,D when following the matrix form in below questions. (You can use python or other languages to find the eigen values and other operation for this question): 1. For the given graph, write down the degree matrix, adjacency matrix, and Laplacian matrix representation. 2.Find the eigenvalues and eigenvectors of the graph Laplacian matrix. Do you see any pattern pertaining to the signs of the eigenvalues (all positive or negative or no such pattern). Will it be same for all such graph Laplacian matrices, and why?
