A.1 The Derivation of Approximate Von Neumann Entropy on Temporal Network In the following, We commence by summarizing the approximation of the undirected graph von Neumann entropy presented by [27]. The best results in each column are highlighted in bold font and the second-best results are underlined. As a result, The expression of the approximate entropy is quadratic in the number of nodes. B.1 Performances in Average Precision Table 3 reports the detailed transductive and inductive link prediction results of AP. B.2 Time Comparison Figure 1 compares the training times of ESSEN against the second-strongest baseline NTW.
