摘要
为了得到性能优越的SVM预测模型,实现城市交通流量的准确预测,文中提出基于遗传算法优化支持向量机(GA-SVM)的城市交通流量预测方法.其中通过遗传算法对SVM中的训练参数进行优化处理,以得到优化的SVM预测模型.实验结果表明:用GA-SVM对城市交通流量预测,预测精度远优于人工神经网络.
In order to gain the excellent SVM forecasting model and realize the accurate forecasting of urban traffic flow,support vector machine optimized by genetic algorithm is presented to forecast urban traffic flow.Genetic algorithm(GA)is introduced to optimize the parameters of support vector machine in this model,which can gain optimized SVM forecasting model.The experimental results indicate that the proposed GA-SVM model has better forecasting accuracy than artificial neural networks.
