摘要 

【目的】将跨市场跨来源情感分析引入人民币汇率预测模型中,提升汇率趋势的预测效果。【方法】构建融合跨市场跨来源情感分析的CCSA-DL模型:采用BERT-TextCNN模型分别提取中美两国官方媒体与个人投资者的深层情感特征,并与基于LSTM的汇率时序深层特征实现融合共享,在此基础上借助SVM模型实现汇率预测。【结果】与基线模型相比,CCSA-DL模型在预测指标和经济收益的表现上均达到最优,尤其与LSTM预测模型对比,在3个评价指标上有平均约16.77%的提升。【局限】情感分析数据来源有待进一步拓展和优化。【结论】引入跨市场跨来源情感分析的CCSA-DL模型具有较优的汇率预测效果和经济收益。

Abstract

[Objective] This study aims to introduce cross-market and cross-source sentiment analysis into the RMB exchange rate forecasting model to improve the performance. [Methods] We built a CCSA-DL model for fusing cross-market and cross-source sentiment analysis. First, we used a BERT-TextCNN model to extract deep sentiment features from China and the United States respectively. Then, we shared them with LSTM-based deep features of exchange rate time series to achieve deep fusion, based on which exchange rate forecasting is realized with the help of SVM model. [Results] Compared with the baseline model, the CCSA-DL model achieved optimal performance in predicting indicators and economic returns. Especially compared with the LSTM prediction model, there was an average improvement of about 16.77% in the three evaluation indicators. [Limitations] The source of sentiment analysis data needs to be further expanded and optimized. [Conclusions] The CCSA-DL model with cross-market and cross-source sentiment analysis has better exchange rate forecasting performance and economic returns.
