In 2019, Dr. Hayase completed his Ph.D. in Mathematical Sciences at the Graduate School of Mathematical Sciences at the University of Tokyo. His doctoral research concerned machine learning using random matrices, free probability theory, and operator algebras. During his time at the graduate school, he worked as an intern in machine learning at Morpho, Inc. and Preferred Networks (PFN), and tackled model compression of deep neural networks. He has also been playing on various social virtual reality platforms since his time at graduate school, with his play time totaling a few thousand hours. After graduating, he conducted research on theoretical research on deep neural networks, contrastive learning, and transfer learning at Fujitsu’s Artificial Intelligence Laboratory, while working as a part-time lecturer (Information Science) at Ochanomizu University. Discovering the appeal of researching the metaverse while working as a world creator in social virtual realities, he joined Cluster Metaverse Lab as the first researcher in 2022.
