Abstract

To improve the spatial reduction rate of the processed dataset and adjust the rand coefficient, this paper designs a method for removing duplicate values in enterprise financial big databased on dynamic grid generation technology. Firstly, denoising of enterprise financial big data is implemented through fast orthogonal wavelet transform. Secondly, based on dynamic grid generation technology, the fusion correlation features of enterprise financial data are constructed, and the correlation degree between data is calculated. Finally, use similarity clustering algorithms to cluster data with high correlation. For highly similar data in the same cluster, retain one record and exclude other identical data entries. The experimental results show that after applying this method, the spatial reduction rate of the dataset ranges from 9.61% to 15.55%, and the highest adjusted rand coefficient of the dataset can reach 0.997, indicating that this method effectively achieves the design expectations.
