摘 要:
针对林业资金投资变化的定量预测,提出一种基于改进支持向量机的预测方法。利用滑动时间窗口方法将历年林业资金投资数据构造成时间序列,将其做为数据样本集并由改进支持向量机加以训练以得到预测模型。通过某省近20年的林业资金投资数据实验验证了预测方法的有效性,实验结果表明:与传统预测方法相比,基于改进支持向量机的预测方法明显提高了投资变化预测精度。

摘 要:
Focused on forecast investment forecast,a novel method based on improved support vector machine with particle swarm optimization(SVM-PSO) was proposed,in order to improve forecast accuracy.With sliding time window,history of forestry investment data had been constructed into a time series.In order to obtain forecast model,the time series was trained as sample set by SVM-PSO.Finally,the experiments,whose data is from the forestry investment of nearly 20 years,show that the SVM-PSO forecast method has better performance than the traditions.
