Abstract

The invention discloses a method for building a near-infrared qualitative analysis model. The method includes the steps of (1) collecting near-infrared spectroscopic data of a sample, and determining modeling sample data; (2) preprocessing the modeling sample data; (3) conducting partial least square feature extraction on the modeling sample data; (4) conducting orthogonal linear discriminant analysis feature extraction on the modeling sample data; (5) building the qualitative analysis model with a support vector machine method. The method is accurate, efficient, rapid and free of professional operation.

Description

technical field [0001] The invention relates to a modeling method in the field of near-infrared qualitative analysis, in particular to a method for establishing a near-infrared qualitative analysis model. Background technique [0002] Near Infrared Spectroscopy (Near Infrared Spectroscopy, NIRS) analysis is an analytical method for qualitative and quantitative analysis of organic matter using the material information contained in the near-infrared spectral region. advantages of ingredients. Near-infrared spectroscopy is an indirect analysis technique, which realizes qualitative or quantitative analysis of unknown samples through the establishment of a calibration model. As a green and versatile analytical technique, near-infrared spectroscopy is widely used in agriculture, food, petrochemicals, medicine, forestry, textiles, mineralogy, and cosmetics. [0003] With the rapid development of analysis technology, various detection technologies based on near-infrared spectrosco...
