DOI: 10.1021/acs.iecr.9b00320
Abstract: Concurrent monitoring schemes that achieve simultaneous process and quality-relevant monitoring have recently attracted much attention. In this Article, we formulate a supervised fault diagnosis framework based on canonical correlation analysis (CCA) with regularization, which includes… read more here.
