摘要: 支持向量机通过结构风险最小化原理来提高泛化能力,现多用于解决小样本的分类问题与回归问题,但用于预测时,单一的模型具有一定的局限性.本文提出一种将改进的多维灰色模型与支持向量机组合预测模型,实现不同模型的优势互补,避免单一模型的局限性,增加模型的稳定性.实验仿真结果表明,所提出的组合预测模型的预测效果明显优于支持向量机和基于新息优先累积法模型,且预测精度相对单一预测模型更高.

Abstract: Support vector machine improves the generalization ability through the principle of structural risk  minimization.It is mostly used to solve the classification problem and regression problem of small samples.However,when used for prediction,a single model has certain limitations.In this paper,an improved multi-dimensional gray model and a support vector machine combined forecasting model are proposed.The combined forecasting model realizes the complementary advantages of different models,and can avoid the limitations of  the single model,increase the stability of the model.The experimental simulation results show that the proposed combined forecast.The prediction effect of the model is significantly better than the support vector machine and the innovation-based prioritization method,the prediction accuracy of the combined prediction  model is higher than that of the single prediction model.
