| Outline of Final Research Achievements |
The brain activity patterns during same cognitive tasks differ between users, and vary depending on situations even within each single user. We developed analysis methods for understanding such heterogeneity of brain measurement data and applied them to real fMRI and EEG data. In order to find common features among users and situations, we also evaluated the noise removal methods that are useful for alleviating fluctuations and constructed a procedure for robust feature extraction. Furthermore, we proposed frameworks of transfer learning based on dictionary learning and multivariate autoregression models towards brain machine interface (BMI) with lower users' burden. We tested their usefulness by using 30 days myoelectric data.
