This research introduces for the first time, to the best of our knowledge, the concept of multimodal learning in bankruptcy prediction models. We use the Conditional Multimodal Discriminative (CMMD) model to learn multimodal representations that embed information from accounting, market, and textual modalities. The CMMD model needs a sample with all data modalities for model training. At test time, the CMMD model only needs access to accounting and market modalities to generate multimodal representations, which are further used to make bankruptcy predictions. This fact makes the use of bankruptcy prediction models using textual data realistic and possible, since accounting and market data are available for all companies unlike textual data. The empirical results in this research show that the classification performance of our proposed methodology is superior compared to that of a large number of traditional classifier models. We also show that our proposed methodology solves the limitation of previous bankruptcy models using textual data, as they can only make predictions for a small proportion of companies. Finally, based on multimodal representations, we introduce an index that is able to capture the uncertainty of the financial situation of companies during periods of financial distress.
翻译:这一研究首次根据我们的知识,在破产预测模型中引入了多式联运学习的概念。我们使用条件性多式联运模式学习包含来自会计、市场和文字模式信息的多式联运代表模式。CMMD模式需要对所有数据模式进行抽样,以进行示范培训。在试验阶段,CMMD模式只需要获得会计和市场模式,才能产生多式联运代表,而这种模式又被进一步用于进行破产预测。这一事实使得破产预测模型的使用现实可行,因为所有公司都可以使用文本数据,因为会计和市场数据与文本数据不同。这一研究的经验结果表明,我们拟议方法的分类性能优于大量传统分类模型。我们还表明,我们拟议的方法解决了以往破产模式使用文本数据的限制,因为它们只能对一小部分公司作出预测。最后,根据多式联运的表述,我们采用了一种指数,能够反映金融困境期间公司财务状况的不确定性。
