Journal ArticleDOI
Using near-infrared spectroscopy and differential adsorption bed method to study adsorption kinetics of orthoxylene on silica gel.
TL;DR: The study has demonstrated the study on the adsorption kinetics of orthoxylene on silica gel with a novel experimental methodology, and discovered that the advertisersorption process was physical adsorbent, and mainly controlled by external diffusion.

Non-invasive detection of medicines and edible products by direct measurement through vials using near-infrared spectroscopy: A review
TL;DR: In this article, the authors provide a review of the non-invasive detection studies using NIR spectra for the quantitative analysis and authenticity/qualitative identification of medicines and edible products in detail, evaluate the experimental design and relevant data analysis methods used, and summarize the problems that should be paid attention to and improvement suggestions when conducting similar research in the future.
Journal ArticleDOI
Input variable scaling for statistical modeling
TL;DR: Two input variable scaling methods for improving the accuracy of soft sensors are proposed that can reduce the negative effects of input variables which are not related to an output variable.

Nearest neighbor pattern classification
Thomas M. Cover,Peter E. Hart +1 more
TL;DR: The nearest neighbor decision rule assigns to an unclassified sample point the classification of the nearest of a set of previously classified points, so it may be said that half the classification information in an infinite sample set is contained in the nearest neighbor.
