This paper describes a complex financial data time series prediction method based on the least square support vector machine(LS-SVM),which changes the inequality restriction in the traditional SVM into an equality restriction and uses the loss function of the quadratic sum of the errors as the empirical function for the training set.
为了解决神经网络算法预测海量金融时间序列数据会出现训练速度慢,内存开销大等问题,提出一种基于最小二乘支持向量机的复杂金融数据时间序列预测方法。
