| Outline of Final Research Achievements |
We tried to apply the semiparametric model to nonparametric Bayesian methods. However, we found that the estimation function method for the semiparametric model is not applicable to the wind data given by AMeDAS we treated in this study. Hence, we introduced CRPS or its extensions to the data, instead, and successfully predicted the wind speed for ten minutes to several hours horizons. In addition, we applied machine learning methods such as nonparametric Bayesian methods to driving data, motion capture data, web data, and mouse behavior data, and showed their effectiveness for modeling and prediction.
