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:

Determination of Chinese liquors from different geographic origins by combination of mass spectrometry and chemometric technique
Pingyan Cheng,Wenlai Fan,Yan Xu +2 more
TL;DR: Wang et al. as discussed by the authors used a combination of partial least squares discriminant analysis (PLS-DA) and stepwise linear discriminant analyses (SLDA) to identify Chinese liquor from different geographic origins.

From classic motor imagery to complex movement intention decoding: The noninvasive Graz-BCI approach
TL;DR: An overview of the Graz-BCI research, from the classic motor imagery detection to complex movement intentions decoding, and the major findings in movement imagination decoding, where the importance of estimating the sources of the discriminative features is emphasized.

TL;DR: Relationships indicate that (1) the hypothalamic-pituitary-adrenal (HPA) axis in East Greenland polar bears is likely to be affected by OHC-contaminants and (2) the association between OHCs and cortisol may be linked with the hypothalamus-pituitsary-thyroid (HPT) axis.

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.
