摘要
针对世界海运需求量预测中存在的非线性、复杂性和不确定性,提出基于LS-SVM(最小二乘支持向量机)世界海运需求量预测模型,通过预测实验,并与其他几种常见模型预测结果比较,表明该模型具有预测精度高、速度快、容易实现等优点。
With consideration of the non-linearity, complexity, and uncertainty of the prediction problem in demand in world shipping, a new prediction model for demand in world shipping based on L^SVM （least squares support vector machine） was put forward. A concrete prediction experiment for demand in world shipping was carried out. Compared with some other models, the model proposed proved to be higher in forecasting speed and accuracy, and easier to realize.
