Application of SVR in quantitative analysis of wines

Fourier transform infrared spectroscopy has been widely used in some related fields,thus induces the rapid development of quantitative analysis method based on Lambert-Beer's Law and chemometrics in recent years.The selection of appropriate pre-processing method and calibration model is extremely crucial to the quantitative analysis.The present paper selected30wine samples and used infrared spectroscopy combined with vector regression algorithm SVR quantitative analysis model with standard normal variate,baseline correction and outliers elimination to analyze four representative components of wine.Satisfactory results were gained while the relative errors were limited to less than 5%.This method can be applied to the wine representative quantitative analysis for the material content.
