基于粒子群优化算法的高斯混合模型和高斯混合回归用于橄榄油品质分析

摘要

随着橄榄油掺假现象日趋严重，寻找一种简单有效的鉴伪分析方法至关重要。采用基于粒子群优化的高斯混合模型和高斯混合回归结合傅里叶变换红外光谱对橄榄油掺假样品进行定性和定量分析，取得了较好的分析结果。%In recent years,olive oil adulteration phenomenon has become increasingly serious. Looking for a simple and effective detection method is very important. In this paper,an improved Gaussian mixture model and Gaussian mixture regression based on particle swarm combined with FT-IR spectrum was used to classify and quantify the adulteration in olive oil and has obtained a good analysis result.
