电子交易中的 Transformer 与 LSTM 比较

研究问题
在高频限价订单簿预测任务中,Transformer 能否优于 LSTM,其相对表现是否因绝对价格、价格差分和价格变动目标而改变?
方法与思路
作者比较多种 LSTM 与 Transformer 模型,提出新的 DLSTM 模型及适配金融预测的 Transformer 架构,并在多项订单簿任务上实验。
材料陈述的贡献
摘要称 Transformer 仅在绝对价格序列预测上具有有限优势,而 LSTM 类模型在价格差分和价格变动预测中表现更好且更稳健。
阅读关注点
应核对订单簿样本、预测期限、时间划分与调参预算、各任务损失函数,以及模型优势是否跨市场和不同时间段保持。
阅读边界
这是 arXiv 预印本,同行评审及期刊接收均未核实;摘要未给出比较数值、交易成本或收益结果,预测表现不能推出盈利能力。

原文摘要

With the rapid development of artificial intelligence, long short term memory (LSTM), one kind of recurrent neural network (RNN), has been widely applied in time series prediction. Like RNN, Transformer is designed to handle the sequential data. As Transformer achieved great success in Natural Language Processing (NLP), researchers got interested in Transformer's performance on time series prediction, and plenty of Transformer-based solutions on long time series forecasting have come out recently. However, when it comes to financial time series prediction, LSTM is still a dominant architecture. Therefore, the question this study wants to answer is: whether the Transformer-based model can be applied in financial time series prediction and beat LSTM. To answer this question, various LSTM-based and Transformer-based models are compared on multiple financial prediction tasks based on high-frequency limit order book data. A new LSTM-based model called DLSTM is built and new architecture for the Transformer-based model is designed to adapt for financial prediction. The experiment result reflects that the Transformer-based model only has the limited advantage in absolute price sequence prediction. The LSTM-based models show better and more robust performance on difference sequence prediction, such as price difference and price movement.
