本文介绍一种对非平稳时间序列建模的新方法.参考Janos Abonyi提出的应用于时间序列的模糊分块算法
将该算法与改进的支持向量回归模型结合起来.首先
提出一种改进的支持向量回归的表达形式;然后
通过启发式的加权方法将模糊分块的信息与SVR结合起来;最后
提出一种基于组合SVR的建模方法.实验结果表明
本文提出的方法对于非平稳时间序列的建模具有较高的实用价值.
A new approach for modeling non-stationary time series was introduced in this paper.Combine the fuzzy segmentation which was proposed by Janos Abonyi with Support Vector Machines(SVMs).Firstly
a modified Support Vector Regression(SVR) was proposed;Secondly
fuzzy segment information was combined with SVR by heuristic weighting method;Thirdly
we discussed a model based on multi-SVR.Experimental results show that the method proposed in this paper has great practical values for non-stationary time series modeling.
