C4.5决策树法在空气质量评价中的应用

摘要

空气质量评价是确定空气污染程度的一种手段,采用先进的人工智能技术对空气环境进行智能评价和预测,成为一个新兴交叉研究领域.采用C4.5决策树算法构建空气质量评价系统,挖掘空气污染物和空气等级关系的历史数据,建立空气污染物-空气等级智能评价模型.通过实验仿真发现,C4.5决策树算法取得了较为理想的分类预测效果.%Intelligent evaluation for air quality is a way which can decide the degree of air pollutant. Intelligent evaluation and prediction by artificial intelligence technology becomes a new crossover study field. Intelligent evaluation model for air quality based on C4.5 decision tree algorithm is established through the historical data of air pollutants and air quality classes. The results of experiments demonstrated that C4.5 decision tree algorithm can obtain good results of classification.
