云环境下基于线性回归算法的PM10—能见度—湿度相关性研究
Research on PM10 -Visibility-Humidity Correlation Based on Linear Regression Algorithm in Cloud Environment
【摘要】 当前基于云平台下线性回归算法用于能见度、湿度与气溶胶PM10之间相关性研究较少,针对现代大规模数据线性回归在单机计算时间过长的问题,设计云环境下DMLR(Distributed Multiple Linear Regression)模型用于能见度、湿度与气溶胶PM10相关性的研究,实验分析表明,湿度区间一致大气气溶胶PM10浓度越大能见度就越小,能见度区间一致大气气溶胶PM10浓度越低湿度越大。实验结果还发现湿度介于40%-90%,能见度介于8km-19kmDMLR预测效果最好。DMLR算法模型在时间性能方面要优于传统回归模型。
【Abstract】 At present,there are few researches on the correlation between visibility,humidity and aerosol PM10 based on the linear regression algorithm under the current cloud platform.For the problem that the linear computing of modern large-scale data is too long in the single machine,DMLR(Distributed Multiple Linear)is designed in the cloud environment.Regression model is used to study the correlation between visibility,humidity and aerosol PM10.The experimental analysis showed that the higher the concentration of atmospheric aerosol PM10 concentration,the smaller the visibility,and the lower the concentration of atmospheric aerosol PM10 concentration.The experimental results also show that the humidity is between 40% and 90%,and the visibility is best when the visibility is between 8 km and 19 km.The DMLR algorithm model outperforms the traditional regression model in terms of temporal performance.
