| 中文摘要:选用2008~2015共8年数据，首先基于高斯核的支持向量机在沪市A股上构建周期性的投资组合，并通过误差图和评价指标与BP神经网络、广义回归神经网络进行比较，结果表明了支持向量机在股票预测上更具有优势.再将改进遗传算法运用于上证股票市场构建最优投资组合，以上证指数作为基准进行比较，得出混合遗传算法优化组合的模型相比单一模型更为有效. |

| Abstract:Based on the Gaussian kernel support vector machine,a portfolio was formed in Shanghai stock market and was compared with the Back propagation neural network and Generalized regression neural network by the relative error figure and some evaluations.The results indicate that support vector machine has the added advantage at stock prediction. The daily price data from January 2008 to December 2015 were used to illustrate the application of support vector machine and genetic algorithm to construct the optimal portfolio in Shanghai stock market, which made a contrast with the benchmark of Shanghai composite index. The results turn out that genetic algorithm optimizes the investment portfolio, and the hybrid model is more effective than a single model. |
