Abstract: Based on deep learning, six layer long short-term memory neural networks are constructed. Eight long short-term memory neural networks are combined with bagging method in ensemble learning and predicting model of neural networks ensemble learning is used in Chinese Stock Market. The experiment tests Shanghai Composite Index, Shenzhen Composite Index, Shanghai Stock Exchange 50 Index, Shanghai-Shenzhen 300 Index, Medium and Small Plate Index and Gem Index during the period from January 4, 2012 to December 29, 2017. The model’s accuracy is 58.5%, precision is 58.33%, recall is 73.5%, [F1] value is 64.5%, and AUC value is 57.67%, which reflect a good prediction outcome.
