From Statistical physics to computer science and back...

Hot News!!

* Wanna learn Deep Learning? Marc Lelarge, Andrei Bursuc and myself are giving a (post-graduate) set of lecture in Ecole Normale this fall called Deep Learning: Do-it-Yourself

* I am looking for Oustanding post-docs to study (deep) machine learning problems. We are looking for both maths (probability, statistics), statistical physics, and machine learning candidates.

* I recently founded a start-up called LightOn, where we aim to solve machine learning problems (litteraly) at the speed of light!

* Our book on "Statistical Physics, Optimization, Inference, and Message-Passing Algorithms" that contains all the lectures from the 2014 Les Houches School has been published by Oxford Press.

* Our review on Statistical Physics of Inference is published in Advances in Physics.

Research Interests

* Statistical Inference * Inverse problems on graphs * Statistical physics of disordered systems * Quantum Computations * Constraint Optimization Problems * Error correction and Information theory * Neural networks * Machine learning
