Outline of Final Research Achievements

We collected EEG and fMRI data during resting and tasks that required concentration, such as motor imagery training. By utilizing these data, we conducted two international joint researches and developed various analysis and decoding methods for neuroimaging data. First, we constructed nonlinear independent component analysis methods such as local space-contrastive learning (LSCL) and independent innovation analysis (IIA) with our collaborator Professor Hyvarinen (University of Helsinki). Second, with Professor Hunt (University of Oxford) and others, we have developed machine learning methods for extracting causal relationships among multiple brain region activities such as demixed shared component analysis (dSCA) and Neural dSCA. Based on these results, we implemented a visualization system for the brain states during concentration training.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発されたLSCLやIIAなどの非線形独立成分分析法は、データを生成している真の統計モデルの識別可能性が数学的に証明されており、このような保証を持たない深層ニューラルネットワークが主流の機械学習コミュニティでも注目されている。この成果やdSCAなどの手法を様々な脳イメージングデータに適用することで、脳活動の時間ダイナミクス構造や複数領野間の情報の流れを解明することができれば、ヒト神経科学の進展に大きく寄与する。これらの脳情報解析法は、ATRが実施中のプロジェクトで今後も活用され、メンタルヘルスの維持に資するブレイン・マシン・インタフェースの研究を通じて社会への貢献が期待される。
