Causal Discovery | 因果探索
Our research group in Data Science and AI develops mathematical methodologies to elucidate the causal mechanisms underlying natural phenomena and human behavior. In particular, we focus on creating statistical methods for estimating causal relationships from observational data obtained outside the context of randomized experiments, aiming to establish a new methodological framework that transcends conventional limitations. Additionally, through collaboration with researchers in a broad range of disciplines, we strive to contribute to solving problems in both basic sciences—such as the natural and social sciences—and applied fields including engineering and medicine.
データサイエンス・AIの研究室です。特徴は、自然現象や人間行動の根底にある因果メカニズムを解明するための数理的方法論に関する研究です。特に、介入のない観察データから因果関係を推測するための数学的方法論を研究開発し、従来の限界を超える新しい方法論体系を構築します。また、 様々な科学分野の研究者と協力して自然科学・社会科学などの基礎科学や工学・医学などの応用科学の問題にも取り組み、方法論の立場から問題の解決に貢献することを目指します。
