Analytical Figures of Merit for Partial Least-Squares Coupled to Residual Multilinearization
(American Chemical Society, 2012-12)
A new expression is developed which allows estimating the sensitivity for the whole family of multivariate calibration algorithms based on partial least-squares regression combined with residual multilinearization. The ...
Multidimensional compressed sensing and their applications
(Wiley, 2013-10-18)
Compressed Sensing (CS) comprises a set of relatively new techniques that exploit the underlying structure of data sets allowing their reconstruction from compressed versions or incomplete information. CS reconstruction ...
Multiway calibration strategy with chromatographic data exploiting the second-order advantage for quantitation of three antidiabetic and three antihypertensive drugs in serum samples
(Elsevier Science, 2018-01)
This paper proposes a multiway calibration strategy implementing the modeling with MCR-ALS and U-PLS/RBL of second-order chromatographic data for quantitation of six analytes: gliclazide, glibenclamide, glimepiride, atenolol, ...
Tensor decompositions for signal processing applications: from two-way to multiway component analysis
(Institute of Electrical and Electronics Engineers, 2015-03)
The widespread use of multi-sensor technology and the emergence of big datasets has highlighted the limitations of standard flat-view matrix models and the necessity to move towards more versatile multi-way data analysis ...
Third order chromatographic-excitation–emission fluorescence data: Advances, challenges and prospects in analytical applications
