Léon Zheng

I am a third-year PhD student at valeo.ai and École normale supérieure de Lyon (LIP, Inria OKCHAM), under the supervision of Rémi Gribonval, Patrick Pérez, Gilles Puy and Elisa Riccietti. I graduated from École Polytechnique (X2016) and Master M2 “Mathématiques, Vision, Apprentissage” at ENS Paris-Saclay in 2020.

My current research is focused on sparse matrix factorization, butterfly factorization, neural network compression with sparsity, parameter-efficient fine-tuning, and self-supervised learning for image representations.

I am looking for a post-doc position in academia or a researcher position in industry starting from May 2024, feel free to contact me.
