Nonlinear Partial Least Squares An Overview

  title={Nonlinear Partial Least Squares An Overview},
  author={Roman Rosipal},
In many areas of research and industrial situations, including many data analytic problems in chemistry, a strong nonlinear relation between different sets of data may exist. While linear models may be a good simple approximation to these problems, when nonlinearity is severe they often perform unacceptably. The nonlinear partial least squares (PLS) method was developed in the area of chemical data analysis. A specific feature of PLS is that relations between sets of observed variables are…

The Application of Nonlinear Partial Least Square to Batch Processes

Abstract Multivariate statistical process control (MSPC) techniques play an important role in industrial batch process monitoring and control. One particularly popular approach to MSPC is partial

Nonlinear sparse partial least squares: an investigation of the effect of nonlinearity and sparsity on the decoding of intracranial data

A new version of nonlinear PLS, namely nonlinear sparse PLS (NLS PLS) is developed, which considers a polynomial relationship between the latent variables and used the lasso penalization in the latent space to avoid overfitting and to improve the decoding accuracy.

Global sensitivity analysis in high dimensions with PLS-PCE


This work formulates an estimate of the combined estimation error for both the subspace identified in the dimension reduction step and the surrogate model constructed therein and demonstrates the performance of this approach with a series of high-dimensional example problems featuring a number of well-known caveats for reliability methods.

Kernel Multivariate Analysis Framework for Supervised Subspace Learning: A Tutorial on Linear and Kernel Multivariate Methods

This article provides a uniform treatment of several methods: principal component analysis (PCA), partial least squares (PLS), canonical correlation analysis (CCA), and orthonormalized PLS (OPLS), as well as their nonlinear extensions derived by means of the theory of reproducing kernel Hilbert spaces (RKHSs).

Kernel Partial Least Square Regression with High Resistance to Multiple Outliers and Bad Leverage Points on Near-Infrared Spectral Data Analysis

Robust alternatives to the existing kernel partial least square (KPLS) regression and the kernel partial robust modified GM6-estimator (KPRMGM6) regression are introduced, which are found to be superior to the robust KPRGM6 and non-robust KPLS.



Nonlinear Partial Least Squares Modeling of Phenyl Alkylamines with the Monoamine Oxidase Inhibitory Activities

This paper has carried out the QSAR analysis of four monoamine oxidase (MAO) inhibitory activities using the nonlinear PLS method, and the structural requirements could be estimated and the utility of the non linear P LS method was demonstrated.

Overview and Recent Advances in Partial Least Squares

Partial Least Squares is a wide class of methods for modeling relations between sets of observed variables by means of latent variables as well as dimension reduction techniques and modeling tools.

Partial Least Squares Regression

PLSR—or PLSR1—is a regression method for collinear data, and can be seen as a competitor to principal component regression.

An overview on the shrinkage properties of partial least squares regression

It is pointed out that experiments on simulated and real world data show that bounding the absolute value of the PLS shrinkage factors by 1 seems to leads to a lower mean squared error.

Partial least squares for discrimination

Partial least squares (PLS) was not originally designed as a tool for statistical discrimination. In spite of this, applied scientists routinely use PLS for classification and there is substantial
