报告内容:
In this talk, a functional kernel entropy component analysis (KECA) is proposed for industrial processes fault detection. Firstly, the industrial process data is transformed into functional data by introducing the rough penalty term in the curve fitting process, which can effectively eliminate the abnormal value and noise interference, and make up for the missing data. Secondly, the functional data is mapped to the high-dimensional linear feature space through the radial basis function. Thirdly, the entropy cumulative contribution in descending order is proposed to determine the number of principal components. Finally, the effectiveness and merits of the proposed method is verified in the Tennessee Eastman process.
