An Improved Mixture of Probabilistic PCA for Nonlinear Data-Driven Process Monitoring
An Improved Mixture of Probabilistic PCA for Nonlinear Data-Driven Process Monitoring
An improved mixture of probabilistic principal component analysis (PPCA) has been introduced for nonlinear data-driven process monitoring in this paper. To realize this purpose, the technique of a mixture of probabilistic principal component analysers is utilized to establish the model of the underlying nonlinear process with local PPCA models, where …
