项目摘要

In recent years, the financial markets have faced significant challenges such as the 2018 bitcoin price crashes and the 2020 US stock market declines. While previous research has largely focused on analyzing price data, this researcher sought to take a novel approach by incorporating natural language data such as news articles. Deep learning techniques were employed to process both price and language data within a single computational framework, establishing a connection between these two complex social systems and ultimately enhancing our understanding of financial markets.In the past year, the researcher proposed a generalized model for stock portfolio optimization that integrates natural language data. This model represented a stock with a vector obtained from news articles and identified extreme risk correlations between stocks from these articles, effectively diversifying the risks. This work was accepted for publication in "Knowledge-Based Systems."Additionally, the researcher investigated the limitations of vector representations of stocks in describing complex phenomena like polysemy. To address these limitations, a new representation method using functions instead of vectors was proposed and validated on language data. The method will be further validated on financial markets and has been accepted for publication in "Advances in Neural Information Processing Systems 2022."

近年来，金融市场面临着巨大的挑战，例如2018年比特币价格崩溃和2020年美国股市下跌。尽管以前的研究主要集中在分析价格数据上，但该研究人员试图通过纳入新闻文章等自然语言数据来采用一种新颖的方法。采用深度学习技术来处理单个计算框架内的价格和语言数据，建立了这两个复杂的社交系统之间的联系，并最终增强了我们对金融市场的理解。在过去的一年中，研究人员提出了一个股票投资组合的广义模型整合自然语言数据的优化。该模型代表了从新闻文章获得的向量的股票，并确定了这些文章中股票之间的极端风险相关性，从而有效地使风险多样化。这项工作被接受在“基于知识的系统”中的出版物。此外，研究人员还研究了股票在描述诸如多义之类的复杂现象时的矢量表示的局限性。为了解决这些限制，提出了一种使用函数代替向量的新表示方法，并在语言数据上验证了。该方法将在金融市场上得到进一步验证，并已被接受以在“神经信息处理系统的进步2022”中发表。
