Geometric properties of partial least squares for process monitoring
Projection to latent structures or partial least squares (PLS) produces output-supervised decomposition on inputX, while principal component analysis (PCA) produces unsupervised decomposition of inputX. In this paper, the effect of outputYon theX-space decomposition in PLS is analyzed andgeometric properties of the PLS structure are revealed. Several PLS algorithms are compared in a geometric w...
متن کاملLeast{squares Multirate FIR Filters
The authors propose a new least{squares design procedure for multirate FIR lters with any desired shape of the (band{limited) frequency response. The aliasing, inherent in such systems, is implicitly taken into account in the approximation criterion.
متن کاملBoosting Weighted Partial Least Squares for Batch Process Quality Prediction
In batch processes, end-product qualities are cumulatively determined by variable dynamic trajectories throughout each batch. Meanwhile, batch processes are inherently time-varying, implying that process variables may have different impacts on end-qualities at different time intervals. To take both the cumulative and the time-varying effects into better consideration for quality prediction, a b...
متن کاملPartial Least Squares for Discrimination
Partial least squares (PLS) was not originally designed as a tool for statistical discrimination. In spite of this, applied scientists routinely use PLS for classification and there is substantial empirical evidence to suggest that it performs well in that role. The interesting question is: why can a procedure that is principally designed for overdetermined regression problems locate and emphas...
متن کاملPartial least squares methods: partial least squares correlation and partial least square regression.
Partial least square (PLS) methods (also sometimes called projection to latent structures) relate the information present in two data tables that collect measurements on the same set of observations. PLS methods proceed by deriving latent variables which are (optimal) linear combinations of the variables of a data table. When the goal is to find the shared information between two tables, the ap...
