| Outline of Final Research Achievements |
In this study, we aimed to explore different but related research areas (mathematical optimization, financial engineering and machine learning). Before this study, we have incorporated risk measures, which are investigated in financial engineering (mainly, VaR and CVaR), into machine learning problems. On the other hand, this study brought generalization theories, which are developed in machine learning, into financial engineering based on an expectation that we might obtain a new portfolio optimization model having high prediction accuracy. Indeed, we could construct such a new portfolio optimization model which has a theoretical guarantee on high prediction accuracy and devise an efficient algorithm to solve the optimization model. Our numerical experiments supported the theoretical guarantee of the proposed model.
