“…There are a number of MSPC tools that are available to help interpret process data, the most commonly applied methods being Principal Component Analysis (PCA) and Partial Least Squares (PLS). On the basis of the results obtained in previous studies by the authors and other researchers (9,11,12), PCA was believed to be a suitable algorithm to apply to the problem discussed here. A brief description of PCA is provided below, and further details of the algorithm are provided in ref 13.…”

“…To overcome the problems associated with univariate SPC, multivariate SPC (MSPC) techniques have been developed (9) and subsequently applied to batch fermentation systems. Preliminary results reported in the literature indicate the suitability of this approach to industrial fermentation systems.…”

“…From the shape of the CGF, the optimum number of PCs is estimated. Eastment and Krzanowski [3] and Nomikos and MacGregor [4] suggested the use of cross-validation when the PCA model is going to be used for future observations, which are independent of the calibration data. This is because cross-validation allows the estimation of the prediction error expected for incoming data.…”

“…Multivariate statistical methods, such as principal component analysis (PCA) and partial least squares (PLS), are widely used in industry for process monitoring (Nomikos and MacGregor, 1995;Qin, 2003;Ge and Song, 2008;Garcia-Alvarez et al, 2012). Other complementary multivariate statistical process monitoring methods, including canonical variate analysis, kernel PCA, dynamic PCA, and independent component analysis, have been proposed to address the limitations of PCA-or PLSbased monitoring strategies (Russell et al, 2000;Juricek et al, 2004;Lee et al, 2004a;2006).…”
