Enhanced detection of accounting fraud using a CNN-LSTM-Attention model optimized by Sparrow search

Data: copy the following files into the same folder with the code files
- matching_data.xlsx and discriminant_variables.csv/zip are RAW data files
- data.xlsx contains selected features after using PCA

MATLAB code:
- SSA.m: the Sparrow search algorithm
- initialization.m: the init function for the Sparrow search
- fical.m: the fitness function for the Sparrow search
- model_*: code for a specific model. Run each file for reproducing the reported results.
