Abstract

A novel process monitoring method based on ReliefF-slow feature analysis (ReliefF-SFA) is proposed, to solve the problem of the large variable dimensions and feature selection. First, the data is mapped into a new space, and the slow characteristics of the data is obtained. The new obtained can not only extract the slowest changing components, but represent the inherent characteristics of the system. Second, the feature selection algorithm ReliefF is used to select the more weighted features, to achieve dimensionality reduction. The main subspace is established based on the obtained features, and the remaining features are put into the residual space. The corresponding statistics and control limits are calculated based on the two subspace. Finally, the process monitoring using the proposed algorithm is performed by testing the actual heat treatment furnace process data, and the results show the effectiveness of the proposed method.
