摘要:Abstract(#br)Wavelength selection is often used for multivariate calibration methods to lower prediction error for the calibrated sample properties. As a result, there are a plethora of wavelength selection methods to select from; all with unique advantages and disadvantages. All...

摘要:... In this study, a correlation-analysis-based wavelength selection method (CAWS) is proposed for calibration transfer. This method relies on the selection of wavelengths at which the spectral responses of master and slave instruments are well correlated (high absolute values of...

摘要:Abstract(#br)For researchers interested in the quantitative analysis of mixture components by terahertz time-domain spectroscopy, the wavelength selection of the full spectrum obtained by the experiments is of great importance. The full spectrum is not only composed of the mixtu...

摘要:... A modified ant colony optimization (ACO) algorithm for wavelength selection in Vis-NIR spectral analysis was proposed to improve the prediction performance of partial least squares regression (PLSR) model. The result proved that feature wavelengths/variables can be selected b...

摘要:... In order to remove redundant information, a more effective wavelength selection method has been presented in this paper. In contrast to many common wavelength selection methods, this method is based on sensing mechanism which has a clear mechanism and can effectively avoid th...

摘要:... It also proposes the use of the support vector regression – recursive feature elimination (SVR-RFE) algorithm to select the most informative wavelengths for SVR models. Models based on full spectra were built using SVR and PLS, while wavelength selection methods were c...

摘要:Abstract(#br)A new strategy based on sampling error profile analysis (SEPA) combined with least absolute shrinkage and selection operator (SEPA-LASSO) was proposed. LASSO has been proven to be effective for multivariate calibration with automatic variable selection for high-dimen...

摘要:... So far comparative research that focuses on the relation between spectral preprocessing, wavelength selection, and model performance is rare. This paper aims to explore the effect of spectral preprocessing and wavelengths selection on the performance of partial least squ...

摘要:Abstract(#br)This article presents an active wavelength selection algorithm for multicomponent analysis with tunable infrared sensors. Traditional techniques for wavelength selection operate off-line; as a result, the resulting feature subset is fixed and only optimal for the spe...

摘要:... The detection wavelengths of the MSL system can be geared toward the specific application purposes. Therefore, it’s important to conduct the wavelength selection work to maximize the potential of the MSL system in vegetation monitoring. Traditional strategies of wavelength selection...
