Log Likelihood Monitoring for Multimode Process Using Variational Bayesian Mixture Factor Analysis Model

Log Likelihood Monitoring for Multimode Process Using Variational Bayesian Mixture Factor Analysis Model

When a traditional mixture factor analysis (MFA) model is used for multimode process monitoring, the determination of parameter is complex, and the construction of monitoring statistics only considers the expectation in probability distributions of factor space and residual space. In this paper, a n...
