Short Bio

I am Lilian Besson, a former student in Mathematics and Computer Science at ENS de Cachan. I am a passionate programmer, open-source enthusiast and young researcher in machine learning, learning theory and cognitive radio.

In 2016-2017 and for the next two years:

Fake picture of me



For my Ph.D., my research is in applied machine learning, focussed on low-cost online learning algorithm with limited feedback (bandit feedback), mainly applied to cognitive radio problems for Opportunistic Spectrum Access and setting up reliable network access protocol for the future Internet of Things networks. By studying and applying classical and recent Multi-Armed Bandit algorithms to carefully designed radio models, we are able to prove some performance guarantees, both numerically in simulations and theoretically with statistical proofs.

My wish is to become a tenured full-time teaching professor in a Prepatory School in France, in computer science and/or maths. Ideally, I will be the happiest man on earth if I could spend the next 30 years teaching introductory Computer Science, Python (and the next awesome languages) and algorithmics.


I love to program and write code and documentation , especially in Python for science, GNU Bash for desktop automation, and HTML/CSS/JS for the web. Everything I did and do is open-source and published (using Git), on my GitHub or my Bitbucket profiles. Here are a few things I did since 2012:
