Credit Card Fraud Detection through Parenclitic Network Analysis Table 2 List of topological metrics used to describe the structure of parenclitic networks.
Name Description Maximum node degree [28 ] Maximum degree of all nodes in the network. It is calculated as , being the degree of nodes Entropy of the degree distribution [29 ] Shannon entropy of the distribution of nodes degrees. It is given by , being the probability of finding a node of degree . Assortativity [28 ] Pearson’s correlation coefficient between the degree of connected nodes. Clustering coefficient [28 ] Measure of the presence of triangles in the network. It is defined as the number of triangles (groups of three fully-connected nodes) over the number of connected triplets (groups of three nodes connected by at least two links). Geodesic distance [28 ] Average length of the shortest path connecting pairs of nodes. Efficiency [30 ] Inverse of the harmonic mean of the length of all shortest distances. Information Content [31 ] Metric assessing the presence of meso-scale structures in the network.
