应用支持向量机、模糊逻辑进行汇率预测与交易
首发时间:2011-11-22
摘要:这篇文章研究了SVM(支持向量机)和FIS(模糊逻辑推理系统)在汇率预测领域的应用,并根据模型的输出进行模拟交易实现损益。我们通过滑动窗口的模式进行阶段式的训练和测试,在每个阶段首先应用遗传算法动态的选取分类特征,然后对径向基、线性、多项式、Sigmoid支持向量机和两种推理精度的Mamdani模糊逻辑推理系统等六个模型进行训练和测试。再选取两种技术中表现最好的两个模型进行联合预测,同时根据联合预测结果进行相应的模拟交易。实验的结果显示我们的联合预测模式给出了比较令人满意的准确率,而相应的交易策略在拥有特定市场走势的测试时期内产生了非常可观的收益。

SVM and fuzzy logic based forex prediction and trading
Abstract:In this paper the application of SVM (support vector machine) and fuzzy logic inference systems in the field of exchange rate forecast is studied, and the simulation of trading gains and losses is carried out according to the output of optimized model. We conduct staged training and testing by the use of sliding window. At each stage we first use genetic algorithms dynamically to select classification features, then we train and test radial basis, linear, polynomial, Sigmoid Support Vector Machines and Mamdani fuzzy logic inference systems of two different precision, thus in total of six models. We select one model with the best performance perspectively from the two machine learning techniques to conduct joint prediction, and simulate trade under the output of joint prediction. The experimental results show that our joint prediction mode gives a more satisfactory accuracy, while the corresponding trading strategy has a very substantial income within a particular market trends in the test period.
