1. IntroductionOBIs are defined as ancient Chinese characters engraved on the shells and bones in the Shang Dynasty more than 3000 years ago. As the earliest systematic Chinese language materials discovered so far, OBIs are hugely valuable to research. In recent years, OBI interpretation and oracle bone rejoining have served as two important research directions in oracle bone science [1]. The purpose of OBI interpretation is to interpret the meaning of OBCs that have not yet been recognized.

Abstract:This paper proposes a method called autoencoder with probabilistic LightGBM (AED-LGB) for detecting credit card frauds. This deep learning-based AED-LGB algorithm first extracts low-dimensional feature data from high-dimensional bank credit card feature data using the characteristics of an autoencoder which has a symmetrical network structure, enhancing the ability of feature representation learning.
