论文摘要
石油公司是世界上最大的公司之一,其在全球股票市场中的经济指标对世界经济\ cite {ec00}的影响很大,并且由于它们与黄金\ cite {ec01}的关系,原油\ cite {ec02}和美元\ cite \ cite {ec03}。这项研究研究了相关特征对长期短期记忆(LSTM)\ Cite {EC04}模型对石油公司股票的可解释性的影响。为了实现这一目标,我们设计了一个标准的长期内存(LSTM)网络,并使用各种相关数据集对其进行了训练。我们的方法旨在通过考虑影响市场的多种因素,例如原油价格,黄金价格和美元来提高股票价格预测的准确性。结果表明,添加与石油库存相关的功能并不能提高LSTM模型的解释性。这些发现表明,尽管LSTM模型可能有效地预测股票价格,但其可解释性可能受到限制。在仅依靠LSTM模型进行股票价格预测时,应谨慎行事,因为它们缺乏可解释性可能会使完全理解推动股票价格变动的基本因素变得困难。考虑到金融市场涵盖了物理复杂系统的一种形式\ cite {ec05},我们已经采用了复杂性分析来支持我们的论点。利用LSTM模型用于金融市场所面临的基本挑战之一在于解释其中意外的反馈动态。
Oil companies are among the largest companies in the world whose economic indicators in the global stock market have a great impact on the world economy\cite{ec00} and market due to their relation to gold\cite{ec01}, crude oil\cite{ec02}, and the dollar\cite{ec03}. This study investigates the impact of correlated features on the interpretability of Long Short-Term Memory(LSTM)\cite{ec04} models for predicting oil company stocks. To achieve this, we designed a Standard Long Short-Term Memory (LSTM) network and trained it using various correlated datasets. Our approach aims to improve the accuracy of stock price prediction by considering the multiple factors affecting the market, such as crude oil prices, gold prices, and the US dollar. The results demonstrate that adding a feature correlated with oil stocks does not improve the interpretability of LSTM models. These findings suggest that while LSTM models may be effective in predicting stock prices, their interpretability may be limited. Caution should be exercised when relying solely on LSTM models for stock price prediction as their lack of interpretability may make it difficult to fully understand the underlying factors driving stock price movements. We have employed complexity analysis to support our argument, considering that financial markets encompass a form of physical complex system\cite{ec05}. One of the fundamental challenges faced in utilizing LSTM models for financial markets lies in interpreting the unexpected feedback dynamics within them.
