Ritvik Choudhary

I'm a researcher at Sony in Tokyo, and a visiting researcher at the ASTREC NICT, working mainly on (large) language models. Lately that means machine translation, post-training, distillation, and sometimes how to make them reason better. Before that, I worked on casual dialogue systems.
