Short bio

Kento Nozawa is an engineer at Preferred Networks, Inc. Recently, he has post-trained in-house LLMs, PLaMo. He completed his Ph.D. under the supervision of Dr. Issei Sato at Issei Sato Lab in The University of Tokyo. Back then, he was working on self-supervised representation learning, especially contrastive representation learning.
