Assistant Professor -- Maître de Conférences Laboratoire Jean Kuntzmann (LJK) , Université Grenoble Alpes Full CV : Français -- Google Scholar Profile Contact : firstname.lastname |a|_ univ-grenoble-alpes.fr or imag.fr CAp 2017 (Conférence sur l'apprentissage automatique) is the 19th annual meeting of the francophone Machine Learning community. The 2017 edition will be held in Grenoble, June 28-30. As the city, characterized by an interdisciplinary culture, the field of machine learning is at the interface of several scientific communities such as computer science, applied mathematics, neuroscience and human sciences. This year, CAp will also feature a learning challenge over Tweets. I am part of the organizing comitee, led by M. Amini. Conference website: cap2017.imag.fr News Mar. 2017 : Our course project on Distributed Optimization for Big Data was granted a development funding from IDEX Grenoble Alpes. The Goal is to raise our Convex and Distributed Optimization to the next level with state of the art technologies (Python/Jupyter, Spark, Docker) and to a wider audience. Nov. 2016 : I gave a tutorial talk about Gossip algorithms at the Machine Learning seminar SMILE in Paris. Slides: Part I -- Gossip algorithms , Part II -- Gossip and Optimization. (The animations may not work with all PDF viewers, they should do fine with Adobe's) Sept. 2016 : Jerome Malick and I taught a concentrated (6h per day during 3 days) Refresher course on Numerical Matrix Analysis and Optimization for students of different Master at Grenoble (MSIAM, MoSig, MSCIT).

This is still a beta version, email me if you have remarks/comments/...! Jan. 2014 : I joined the Alcatel-Lucent Chair on Flexible Radio as a Post-Doc with funding from the ERC More (Advanced Mathematical Tools for Complex Network Engineering) . working mainly with Romain Couillet and Merouane Debbah Dec. 2013 : I defended my Ph.D. thesis entitled Distributed Estimation and Optimization in Asynchronous Networks and prepared at Telecom ParisTech .
