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:

Numerical linear algebra in data mining
TL;DR: The emphasis is on rank reduction as a method of extracting information from a data matrix, low-rank approximation of matrices using the singular value decomposition and clustering, and on eigenvalue methods for network analysis.

Mechanical, water absorption, and aging properties of polypropylene/flax/glass fiber hybrid composites:
TL;DR: In this paper, the mechanical and aging properties of flax/glass fibers reinforced polypropylene hybrid composites were investigated and the mechanical properties as a function of reinforcement content were investigated.

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.
