A Soft Sensor Modeling Method Based on
 SelfAdaptive Fuzzy Gauss Kernel Clustering

Abstract

Abstract: It is difficult for a single model to express the complicated production process, and it often results in low accuracy of prediction and poor performance of generalization. This paper presents a multimodel fusion method based on probability weight and selfadaptive fuzzy Gauss kernel clustering. The method determines cluster centers according to dispersion of the samples in a high dimensional space. The weight of every submodel is given by Bayesian posterior method. The method can overcome the limitation of singlemodel forecast and improve traditional multimodel fusion methods for obtaining higher prediction accuracy.

Key words: adaption, fuzzy Gauss kernel clustering, probabilityweighted, multimodel
