About the seminar

This seminar aims to increase the links between the different laboratories in Saclay in the field of Applied Maths, Statistics and Machine Learning. The Seminar is organized every first Tuesday of the month with 2 presentations followed by a small refreshment. The localization of the seminar will change to accommodate the different labs.

Organization

Due to access restriction, you need to register for the seminar. A link is provided in the description and should also be sent with the seminar announcement. It will also help us organize for the food quantities. If you think you will come, please register! (even if you are unsure)

To not miss the next seminar, please subscribe to the announcement mailing list palaisien@inria.fr.
You can also add the calendar from the seminar to your own calendar (see below).

Radu-Alexandru Dragomir - Theoretical perspectives on particle swarm optimization
Particle Swarm Optimization (PSO) is a class of heuristic methods for gradient-free global minimization. Despite their popularity, the reasons for their sucess remain poorly undernstood. In this talk, I will expose some of the theoretical work in that direction, starting from the mean-field approximation of Pinnau et al. (2016), to our recent work on long-time convergence. In particular, we show that a simplified version of CBO follows, in expectation, a dynamic similar to that of ...

In this talk, I will expose some of the theoretical work in that direction, starting from the mean-field approximation of Pinnau et al. (2016), to our recent work on long-time convergence. In particular, we show that a simplified version of CBO follows, in expectation, a dynamic similar to that of proximal gradient descent. This allows to highlight two phases in the PSO dynamics : a global search phase based on a proximal map followed with a local Gaussian random search.
Joint work with Victor Priser and Pascal Bianchi
