AdaBoost based bankruptcy forecasting of Korean construction companies

- AdaBoost (adaptive boosting) is an appropriate model to judge the financial risk of Korean construction companies.
- We classified construction companies into three groups - large, middle, and small based on the capital of a company.
- We analyzed the predictive ability of the AdaBoost and other algorithms for each group of companies.
- The AdaBoost has more predictive power than others, especially for the large group of companies that has the capital more than 50 billion won.
