The Kullback–Leibler divergence measure is used to compare the original network to its perturbation. By setting the regression coefficients to zero or non-zero values, the proposed method can remove or add arcs, making it possible to compare different network structures. The methodology is implemented with some case studies. eng restricted access Evaluating The Difference Between Graph Structures In Gaussian Bayesian Networks journal article
