ABOUT THE SPEAKER

Tadahiro Taniguchi

Professor · Graduate School of Informatics, Kyoto University

My research explores how language and shared meanings emerge through embodied experience and social interaction. Collective predictive coding connects this question with world modeling, decentralized Bayesian inference and human–AI co-creation.
