Takashi Matsubara研究室は、物理法則を満たす機械学習モデルの開発と、それを用いた動的システムの解析・制御に取り組んでいます。具体的には、ハミルトニアン力学やポート・ハミルトニアンなどの物理的構造を神経回路網に組み込み、エネルギー保存や質量保存といった基本法則を守りながら動的系を学習するモデルを構築しています。これにより、物理シミュレーションの精度向上や、視覚情報からの安定した制御が可能になります。また数値解析の誤差理論を機械学習に応用し、長期予測精度の改善に取り組んでいます。同時に、画像生成・編集やセマンティック・セグメンテーション等の視覚認識タスクに深層学習を応用する研究も進めています。拡散モデルを用いた高品質な画像操作、述語論理による意図表現の改善、スケール不変な畳み込みを用いた深度画像の解析など、ユーザー意図の正確な実現と環境理解の向上を目指しています。さらに、材料工学や暗号化などの応用領域でも、計算資源の効率化やハードウェア実装を検討しています。FPGA上での暗号処理の高速化や、電気化学プロセスを用いた機能性複合膜の製造といった実装的な課題にも取り組み、基礎理論から実応用までの幅広い研究を推進しています。
