TLDR
PLS-regression (PLSR) as mentioned in this paper is the PLS approach in its simplest, and in chemistry and technology, most used form (two-block predictive PLS) is a method for relating two data matrices, X and Y, by a linear multivariate model.About:

Black tea classification employing feature fusion of E-Nose and E-Tongue responses
Mahuya Bhattacharyya Banerjee,Runu Banerjee Roy,Bipan Tudu,Rajib Bandyopadhyay,Rajib Bandyopadhyay,Nabarun Bhattacharyya,Nabarun Bhattacharyya +6 more
TL;DR: Wavelet energy feature (WEF) has been extracted from the responses of e-nose and e-tongue for the classification of different grades of Indian black tea and it is compared with some benchmark classification methods namely PLS-DA and Sammon's projection method which exhibits the superiority of the WEF extraction method combining the responds of multi sensory system.

Brown bears possess anal sacs and secretions may code for sex
Frank Rosell,Susan M. Jojola,Susan M. Jojola,Kristian Ingdal,Bård Andreas Lassen,Jon E. Swenson,Jon M. Arnemo,Andreas Zedrosser,Andreas Zedrosser +8 more
TL;DR: The results confirm that brown bears possess anal sacs, that secretions likely relay information about sex, and suggest other chemical information critical to the bears' social system is encoded in the AGS.

Response of chestnut phenology in China to climate variation and change
TL;DR: Long-term records of chestnut first flowering, leaf coloring and length of the growing season from Beijing, China are evaluated to evaluate the response of tree phenology to warming during different parts of the year.

Prediction of cell culture media performance using fluorescence spectroscopy.
TL;DR: This work has developed robust methods which can be used to identify compositional changes and ultimately predict the efficacy of individual fed batch media in terms of downstream protein product yield with an accuracy of +/-0.13 g/L.

Olivier Fernandez,Maria Urrutia,Stéphane Bernillon,Catherine Giauffret,François Tardieu,Jacques Le Gouis,Nicolas B. Langlade,Alain Charcosset,Annick Moing,Yves Gibon +9 more
TL;DR: It is proposed that metabolic markers are tending to complement and possibly replace traditional molecular markers in plant science as efficient estimators of performance.

A Leisurely Look at the Bootstrap, the Jackknife, and Cross-Validation
Bradley Efron,Gail Gong +1 more
TL;DR: This paper reviewed the nonparametric estimation of statistical error, mainly the bias and standard error of an estimator, or the error rate of a prediction rule, at a relaxed mathematical level, omitting most proofs, regularity conditions and technical details.
