  • 14:30 – 15:00 : Elisa Riccietti « Multilevel Physics Informed Neural Networks »
This talk will focus on the link between finite state models and Recurrent Neural Networks (RNN). These latter models are used for sequential data: text, speech, temporal series, etc. I’ll give an overview of the different results that target the distillation of well-known computational models from an already learned RNN. While most of these works considered the distillation of Deterministic Finite state Automata, I may have time to detail the extraction of Weighted Automata using a spectral approach.
Speaker bio:
Elisa Riccietti is currently associate professor at Ecole Normale Superieure in Lyon, France. Her research revolves around numerical optimization and machine learning. In the past her research focused on the solution of least-squares problems with noisy function and gradient, in particular ill-posed large-scale problems with inexact function and gradient. More recently she is working on the application of multilevel optimization methods to the training of artificial neural networks and mixed-precision methods for machine learning.


  • 15:00 – 15:30 : Rémi Eyraud « Opening the Black-Box: What Formal Language Theory Teaches Us About Recurrent Neural Networks »
Recent practical successes of machine learning – for instance in signal processing, natural language processing, or image retrieval – heavily rely on the training of powerful models such as deep neural networks. However, the decision taken by these models are hard to interpret – they are usually seen as black boxes – and using them can require important amount of computation power.
Speaker bio:
Rémi Eyraud is a junior professor at the Jean Monnet University, France. After the defense of his Ph.D, he moved for a post-doc at the University of Amsterdam, The Netherlands. He then was hired at the Aix-Marseille University, France, as a Maître de Conférences. He then spent a couple of years as an invited researcher at two US East Coast universities: the University of Maryland, Baltimore County and the University of Delaware. He joined the Jean Monnet University in 2020.
