摘要:

在时间序列中提取先前未知的模式和信息是许多实际应用的核心。在这项研究中,我们介绍了一种使用深度学习模型建模金融时间序列的新方法。我们使用一个长短期记忆(LSTM)网络,配备了可训练的初始隐藏状态。通过学习重构时间序列,该模型可以用其参数表示高维时间序列数据。对韩国股票市场数据的实验表明,该模型能够捕捉到大量股票价格在其潜空间中的相对相似性。此外,该模型还可以从潜在空间预测未来股票的走势。该方法可以识别多个时间序列之间的关系,并可应用于金融领域,如投资组合优化。

英文摘要:

Extracting previously unknown patterns and information in time series is central to many real-world applications. In this study, we introduce a novel approach to modeling financial time series using a deep learning model. We use a Long Short-Term Memory (LSTM) network equipped with the trainable initial hidden states. By learning to reconstruct time series, the proposed model can represent high-dimensional time series data with its parameters. An experiment with the Korean stock market data showed that the model was able to capture the relative similarity between a large number of stock prices in its latent space. Besides, the model was also able to predict the future stock trends from the latent space. The proposed method can help to identify relationships among many time series, and it could be applied to financial applications, such as optimizing the investment portfolios.
