| Abstract: | Traditional neighbor preserving embedding(NPE)is not effective in dimensionality reduction of high-dimensional data with multi-center and obvious variance differences.Therefore,an improved LNS and neighbor preserving embedding(MLNS-NPE)algorithm is proposed and applied to fault diagnosis.It used MLNS algorithm to process the data,then carried out NPE algorithm modeling on the processed data.In the process of numerical examples and penicillin fermentation,the comparison results between the algorithm and traditional NPE algorithm,kernel neighborhood preserving embedding algorithm(KNPE)and KNN algorithm show that after the algorithm is adopted,the data multicenter and modal difference are eliminated,which provides a prerequisite for the application of subsequent NPE algorithm.At the same time,compared with other algorithms,the fault detection rate is the highest,and the detection capability of NPE algorithm for multimodal data is improved. |
