Intelligent financial fraud detection practices in post-pandemic era

“…Models performing poorly on the minority may lead to undesirable results, as people are more concerned about the minority classes, i.e., the fraudsters. The class imbalance problem on feature-based neural methods has been studied in depth, such as re-sampling, 162 , 163 , 164 re-weighting, 165 , 166 , 167 , 168 and transfer learning. 95 , 169 Whereas in the GNNs works, the noisy information, few interactions among fraudsters, and desalination of the minority class’s features caused by the message aggregation of GNNs are three major challenges in designing class imbalanced GNNs for fraud detection.…”

Excitation wavelength-dependent tunable color Te4+-doped Cs2ZrCl6 vacancy-ordered perovskites for optical anti-counterfeiting

“…Therefore, it is of practical significance to develop optical anticounterfeiting materials with more complex optical features and higher security. 14,15 NaYF 4 :Ln@NaYF 4 :Ce,Mn (Ln = Yb, Er/Tm) 16 with three light-emitting modes and the BaGdF 5 :Yb,Er/Tm 17 lightemitting material with dual light-emitting modes have been developed by a lanthanide rare earth ion doping strategy, which realizes two light-emitting modes of DCPL and UCPL at the same time in a single material, and greatly enhances the security of the means of anti-counterfeiting. Ln 3+ /Hoc@UIO-66(DPA) (Ln = Eu, Tb) has been found to excite continuous color-changing luminescence in the excitation wavelength range of 250-340 nm.…”
