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
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.
