  • Abstract How to effectively predict financial distress is an important issue in corporate financial management. We use data mining and machine learning methodology to analysis financial statement or financial ratio. Traditional approaches usually formalize financial prediction problem as two-class problem, attempting to differentiate the financially distressed companies (the distressed class) from the normal companies (the non-distressed class). However, there are many factors contributing to a company’s financial crisis. Taiwan Stock Exchange Corporation (TWSE) defines several kinds of financial crisis which show distinct reason. This observation motivates us to further segment the distressed class into a few subclasses. Each subclass corresponds to one crisis type. We propose new methods to design multiple classifier system. Each classifier for a subclass gives a meaningful training set and feature set. It makes that each classifier is professional for each sub-problem. This model is different from the existing approaches that each classifier is not designed for the same pattern recognition problem. The prediction accuracy is superior to traditional approaches by using our prediction model.
