Yann Ollivier's Web Page

The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself. Therefore, all progress depends on the unreasonable man.

G. B. Shaw

About me

My name is Yann Ollivier (Yann is the given name and Ollivier is the family name; a crude English transcription would be Ian Olive-Yeah). I am currently a research scientist at the Facebook Artificial Intelligence lab in Paris, working chiefly on neural networks. I am a mathematician by training.

Curriculum vitæ (not up-to-date).

À propos des enseignants-chercheurs (regarding changes to the organization of research in France initiated by the ministry a few years ago).

These pages are bilingual (English/French), but most documents are available in only one language, hence a single main page with mixed English and French links.
