Abstract: A supervised manifold learning method based on local feature extraction is proposed to improve the quality of industrial product. A new neighborhood search based on multi-class is used to obtain neighborhood matrices. The eigenvalue decomposition is applied to extract the manifold hidden in the data from the neighborhood matrices. At the same time, a monitoring model is built with the training data based on support vector data description (SVDD). If an abnormal sample is detected by SVDD, it will be projected on the manifold to obtain the adjustment values, which make the abnormal sample return to the normal state. The actual production process data of IF steel is conducted to verify the effectiveness of the proposed method. The results show that the new method can extract the essential manifold and optimize the process parameters effectively. So the proposed method can provide a new strategy to optimize the process parameters for the actual production process.
