Predicting Stock index Using Weighted Support Vector Machines;
加权支持向量机在证券指数预测中的研究
2.
As the forecasting of a huge-size financial time series by training a standard SVM (Support Vector Machine) will result in slow training speed and large memory spending, a decomposition-cooperation-weighted SVM regression is put forward and used to predict the stock index.
运用标准支持向量机预测海量金融时间序列数据会出现训练速度慢、内存开销大的问题,文中提出一种分解合作加权的回归支持向量机,将大样本集分解成若干工作子集,分段提炼出支持向量机,同时根据支持向量的重要性给出不同的错误惩罚度,并将其应用于证券指数预测。
3.
