| Outline of Final Research Achievements |
We aim to study the Taguchi method that can be applied to complex data environments. In particular, I focus on research on Taguchi's MT system (Mahalanobis Taguchi system). In addition, I would like to conduct research on Taguchi's experimental design method (robust parameter design) and SN ratio. MT system is a general term for Taguchi's multivariate analysis method, which consists of several analysis methods for anomaly detection and some analysis methods for prediction.
Applicants have made considerable progress in research on the theoretical properties of each analysis method for MT systems and their improvement methods. In the future, we would like to develop a new method for the MT system that is conscious of situations that are more difficult to analyze, such as high-dimensional small sample data, noisy data, missing data, and directional data.
