Mechanical Parameter Analysis of Rock Material via PLSR Model

Key Engineering Materials, 2011
Mechanical parameter analysis is a complicated issue since it is influenced by many factors. Closely related with the influencing factors of compressibility coefficients of rock material (sandstone), this article first introduces the way to process partial least square regression (PLSR) analysis.

Nonlinear system identification using deep belief network based on PLSR

2017 36th Chinese Control Conference (CCC), 2017
Deep learning has been successfully applied into pattern recognition due to its deep architecture and effective unsupervised learning, and deep belief network (DBN) is a popular model based on deep learning technique. In this paper, a DBN identification model based on partial least square regression (PLSR), named PLSR-DBN, is proposed for nonlinear ...

Quantitative determination of Auramine O by terahertz spectroscopy with 2DCOS-PLSR model

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2017
Residues of harmful dyes such as Auramine O (AO) in herb and food products threaten the health of people. So, fast and sensitive detection techniques of the residues are needed. As a powerful tool for substance detection, terahertz (THz) spectroscopy was used for the quantitative determination of AO by combining with an improved partial least-squares ...

Application of PLSR in rapid detection of glucose in sheep serum

, 2020
This paper proposes for the first time to establish grid search-support vector regression (GS-SVR), random forest (RF) and partial least squares regression (PLSR) models based on the measured Raman spectral data of sheep serum to find a method that can ...

Wavelength Selection to Predict Crude Protein in Sorghum using PLSR

2018 Asia Communications and Photonics Conference (ACP), 2018
We have applied PLSR on NIRS data of Sorghum to select significant wavelengths for Crude-Protein content. Calibration models proposed using single wavelength (1449nm) and a pair (1485nm and 1486nm) give the coefficient of determination (R2) as 0.7928 and 0.8334 respectively.

QR-PLSR: Reduced-rank regression for high-speed hardware implementation

Journal of Chemometrics, 1996
A version of PLS regression is described that intends to combine the computer hardware implementation advantages of the algebraic technique of ‘QR decomposition’ with the statistical, interpretative and computational advantages of PLS regression. With a QR decomposition based on Givens rotations, the QR-PLS technique appears to be suited for hardware ...

Dehydration modeling of Cordyceps militaris in mid-infrared-assisted convection drying system: Using low-field nuclear magnetic resonance with the aid of ELM and PLSR

Drying Technology, 2019
The changes in moisture content and shrinkage ratio of Cordyceps militaris during mid-infrared-assisted convection drying (MIRCD) with different drying temperatures (40, 50, and 60 °C) and velocities of airflow (1 and 2 ms−1) were studied.
