Outline of Final Research Achievements

We developed a novel analysis framework for general nonlinear dynamics. The conventional frameworks generally assumed linear dynamics or additive innovation models, which can be restrictive for their applications to complex dynamics including the human brain. Our new framework, unsupervised representation learning based on deep learning with theoretical justification, is designed for such general dynamical models, and gives very general tools for analyzing them.

Academic Significance and Societal Importance of the Research Achievements

一般形の非線形ダイナミクスは不定性が高いことが知られており,同定性を保証した解析法はこれまで存在しなかった.提案法はそのような一般形非線形ダイナミクスの解析を理論的な保証を与えた上で実現するものであり,大きな学術的意義がある.また,提案法は汎用性の高いものであり,様々な対象に広く適用可能なものである.今後様々な理論的拡張が考えられるなど,社会的意義も大きい.
