| Outline of Final Research Achievements |
In this study, we proposed methods based on computational and data-driven approaches for extracting spatiotemporal dynamics in neural systems. For this purpose, we constructed methods for estimating neural systems by means of data-driven approaches by using mathematical models with detailed electrical properties and spatial structure of neural systems. By assimilating spatiotemporal systems extracted by data-driven methods with observed neural activity data, we constructed methods for estimating large-scale neural network models based on observable data.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では，計算科学とデータ駆動科学の融合により，計測データから神経システムの数理モデルの精緻な推定を実現する方法の構築を行った点において神経科学上の学術的意義を有すると考えられる．さらに，本研究では，数理構造の普遍性を抽出することで，スパースモデリングやベイズ推論を代表とするデータ駆動的手法により，神経システムの非線形ダイナミクスの推定のみならず，地球惑星科学などの他の学術領域における非線形ダイナミクスの抽出技術の構築をも行った．すなわち，本研究は，複雑ダイナミクスに従う動的システムをデータ駆動型手法で抽出するための共通的数理基盤を構築したという点においても学術的意義を有すると考えられる．
