摘　　要：针对高校毕业生就业资源信息分类精度差、就业去向预测结果准确率低的问题,提出基于线性二次指数平滑法的高校毕业生就业去向预测方法。构建高校毕业生就业影响因素分析模型,采用随机森林方法对学生数据进行采集与分类。运用Apriori算法将求职信息和高校毕业生的求职要求进行相关性分析。利用一次指数平滑法分析就业单位类型与薪资范围的标准误差,在此基础上,进行二次平滑值估算,通过就业信息类别的二次平滑值调节需要估算的高校毕业生就业去向类别的权重,降低高校毕业生就业去向的预测误差,实现高校毕业生就业去向预测。实验结果表明,该方法在预测毕业生就业去向方面的准确率、召回率、招聘率较高,可以有效地为高校毕业生推荐合理企业岗位。Aiming at the problems of poor classification accuracy of college graduates'employment resources information and low accuracy of employment destination prediction results,this paper puts forward a prediction method of college graduates'employ⁃ment destination based on linear quadratic exponential smoothing method.This paper constructs an analysis model of influencing fac⁃tors of college graduates'employment,predicts the employment rate of college students by using random forest method,and classi⁃fies the results.Using Apriori method,this paper analyzes the correlation between job-seeking information and job-seeking require⁃ments of college graduates.The first exponential smoothing method is used to analyze the standard error between the type of employ⁃ment unit and the salary range.On this basis,the second smoothing value is estimated,and the weight of the employment destina⁃tion category of college graduates to be estimated is adjusted through the second smoothing value of employment information catego⁃ry,so as to reduce the prediction error of the employment destination of college graduates and realize the employment destination prediction of college graduates.The experimental results show that the proposed method has high accuracy and recall rate in predict⁃ing the employment destination of graduates,and can effectively recommend reasonable enterprise positions for college graduates.
