摘　　要：本文主要对LSTM模型结构改进及优化其参数,使其预测股票涨跌走势准确率明显提高,同时对美股周数据及日数据在LSTM神经网络预测效果展开研究.一方面通过分析对比两者预测效果差别,验证不同数据集对预测效果的影响;另一方面为LSTM股票预测研究提供数据集的选择建议,以提高股票预测准确率.本研究通过改进后的LSTM神经网络模型使用多序列股票预测方法来进行股票价格的涨跌趋势预测.实验结果证实,与日数据相比,周数据的预测效果表现更优,其中日数据的平均准确率为52.8%,而周数据的平均准确率为58%,使用周数据训练LSTM模型,股票预测准确率更高.This study mainly optimizes the structure and parameters of the LSTM model,so that the accuracy of predicting the trend in stock prices is significantly improved.Besides,we investigate the weekly and daily data on US stock in terms of predicting the LSTM neural network.On one hand,we compare the difference to verify the impact of different data sets on the forecast.On the other hand,we provide selection suggestions for data sets so as to increase the accuracy of stock forecast.This study uses the multi-time-series stock forecast in the improved LSTM model to predict the trend in stock prices.The results demonstrate that the weekly data perform better in forecast than daily data.To be specific,the average accuracy of daily data and weekly data is 52.8%and 58%,respectively.In summary,the application of weekly data to training the LSTM model yields higher accuracy in stock forecast.
