Valentin Liévin

Machine learning research @ Google Research. Better LLMs for healthcare and science.

I have completed my PhD in Machine Learning with prof. Ole Winther at the Technical University of Denmark (DTU). I worked on generative modeling (Deep VAEs), variational inference, optimization methods, large language models and information retrieval. I submitted my PhD thesis Deep Latent Variable Models for Natural Language Processing in October 2022.
