"Financial fraud" refers to listed companies falsifying financial statements, falsely reporting or concealing part of the financial data of the company. Based on the training data processing of missing value, exception value, standardized processing or other data processing on the training data set, among the 19 major industries in society, processing unbalanced data for 8 industries. Using SVM to select the optimal equilibrium method for each industry, and the remaining 11 industry data do not perform any equalization operations. Subsequently, The Weight, Filter, Wrapper, Embedded and other methods are used to select data characteristics, and combines the actual economic significance to obtain the final characteristics. Finally, through seven models of prediction, using AUC score as evaluation index to predict which listed companies may have fraud. On the premise of not deviating from the actual laws and practical significance, through the self-constructing function and using it to make a heat map. In this way, the similarities and differences of data indicators related to financial fraud of listed companies in different industries are obtained.
