文章摘要：本文基于體檢獲得的血壓、血脂、尿糖和尿酸等數(shù)據(jù)指標(biāo)，應(yīng)用支持向量機(jī)（SVM）對(duì)南方人群冠心病患者和非冠心病患者進(jìn)行分類(lèi)研究，為進(jìn)一步的預(yù)防和治療提供指導(dǎo)。首先選取徑向基核函數(shù)、線性核函數(shù)和多項(xiàng)式核函數(shù)，構(gòu)造了SVM分類(lèi)器，再采用粒子群優(yōu)化（PSO）算法SVM懲罰參數(shù)C和核參數(shù)o，，最后進(jìn)行冠心病的診斷和預(yù)測(cè)。通過(guò)與反向傳播模型的人工神經(jīng)網(wǎng)絡(luò)、線性判別分析法、I，ogistic回歸分析及優(yōu)化前的SVM進(jìn)行比較，我們的計(jì)算結(jié)果顯示優(yōu)化后的RBF—SVM的總體分類(lèi)效果要優(yōu)于其他數(shù)據(jù)挖掘算法，其分類(lèi)準(zhǔn)確率、敏感性和特異性分別高達(dá)94．51％、92．31％及96．67％。研究表明SVM在心血管疾病的預(yù)測(cè)和輔助診斷中有很大的應(yīng)用潛力。

Abstr：Base on the data of blood pressure, plasma lipid, Glu and UA by physical test, Support Vector Machine （SVM） was applied to identify coronary heart disease （CHD） in patients and non-CHD individuals in south China population for guide of further prevention and treatment of the disease. Firstly, the SVM classifier was built using radial basis kernel function, liner kernel function and polynomial kernel function, respectively. Secondly, the SVM penalty factor C and kernel parameter ~ were optimized by particle swarm optimization （PSO） and then employed to diagnose and predict the CHD. By comparison with those from artificial neural network with the back propagation （BP） model, linear discriminant analysis, logistic regression method and non-optimized SVM, the overall results of our calculation demonstrated that the classification performance of optimized RBF-SVM model could be superior to other classifier algorithm with higher accuracy rate, sensitivity and specificity, which were 94.51%, 92.31% and 96.67%respectively. So, it is well concluded that SVM could be used as a valid method for assisting diagnosis of CHD.
