Multi-analyte quantification in bioprocesses by FTIR spectroscopy using Partial Least Squares Regression and Multivariate Curve Resolution
(Elsevier Science, 2014-01)
This paper presents the quantification of Penicillin V and phenoxyacetic acid, a precursor, inline during Pencillium chrysogenum fermentations by FTIR spectroscopy and partial least squares (PLS) regression and multivariate ...
Performance Analysis of the Least-Squares Estimator in Astrometry
(Univ Chicago Press, 2015)
We characterize the performance of the widely used least-squares estimator in astrometry in terms of a comparison with the Cramer-Rao lower variance bound. In this inference context the performance of the least-squares ...
Higher-Order Partial Least Squares (HOPLS) : a generalized multi-linear regression method
(IEEE Computer Society, 2013-07)
A new generalized multilinear regression model, termed the Higher-Order Partial Least Squares (HOPLS), is introduced with the aim to predict a tensor (multiway array) Y from a tensor X through projecting the data onto the ...
Multivariate filters combined with interval partial least square method: A strategy for optimizing PLS models developed with near infrared data of multicomponent solutions
(2019-05-01)
Near infrared spectroscopy (NIR)is a technique capable of rapidly generating rich chemical information. However, many chemical problems are limited to the low sensitivity and selectivity due to the spectral similarity of ...
General two-dimensional least-squares image subtraction
(2010)
A very general two-dimensional solution to the image convolution problem is presented
extending the least-squares approach of Bramich. Image convolution is of wide applicability
in astronomical data reduction including, ...
The minus order and range additivity
(Elsevier Science Inc, 2017-10)
We study the minus order on the algebra of bounded linear operators on a Hilbert space. By giving a characterization in terms of range additivity, we show that the intrinsic nature of the minus order is algebraic. Applications ...
A note on Lanczos generalized derivative

Visible/near infrared-partial least-squares analysis of Brix in sugar cane juice. A test field for variable selection methods
(Elsevier Science, 2010-07)
Several variable selection algorithms were applied in order to sort informative wavelengths for building a partial least-squares (PLS) model relating visible/near infrared spectra to Brix degrees in samples of sugar cane ...
