- Abstract:
-
The problem of missing data is inevitable in different areas. However, traditional data mining algorithms do not process incomplete data sets well. The covariance matrix and its determinant were applied to the fitness function of particle swarm optimization, and the optimal threshold was obtained through iteration. Then, the missing data were reconstructed based on the evolving clustering method using the optimal threshold, which solved the difficulty in optimal threshold selection and determined its influence on data reconstruction results. Furthermore, the randomness of the auto-associative extreme learning machine was removed by invoking the evolving clustering method with the optimal threshold. Finally, six UCI standard data sets and nine activation functions were selected to verify the method. The results showed that compared with most existing reconstruction methods, the proposed hybrid reconstruction method can complete the reconstruction of the missing data more effectively.
