Takuma Yagi, Ph. D.
Research Scientist, National Institute of Advanced Industrial Science and Technology (AIST)

I am a Research Scientist at Artificial Intelligence Research Center, AIST.
I got my Ph.D. degree at the University of Tokyo in 2022, advised by Prof. Yoichi Sato.
I'm especially interested in developing intelligent systems that perceives and understand our world and using them to make our life better.
