Séminaire exceptionnel de Pablo JENSEN : Unexpected link between neural nets and liberalism - 10 janvier 2019, GIPSA-lab


Pablo JENSEN, directeur de recherche CNRS au Laboratoire de Physique de l'ENS de Lyon est l'invité d'un séminaire exceptionnel intitulé "The unexpected link between neural nets and liberalism". Il aura lieu à GIPSA-lab, le 10 janvier 2019 à 10h30 en Salle Mont-Blanc.

Sixty years ago, Arthur Rosenblatt, a psychologist working for the army invented the perceptron, the first neural network capable of learning. Unexpectedly, Rosenblatt cites, as a major source of inspiration, an economist: Friedrich Hayek. He is well-known for his 1974 Nobel prize… and by his ultra-liberal stances, justifying the Pinochet coup in a Chilean newspaper: «Personally, I prefer a liberal dictator to a democratic government that lacks liberalism». This talk presents ongoing work on the link between Hayek’s ideology and neural networks.


After a PhD on experimental condensed-matter physics, Pablo JENSEN worked for 15 years on the modeling of nanostructure growth. This lead to major publications in top journals, including Nature, Phys Rev Lett and a widely cited review in Rev Mod Phys. After these achievements, he decided to follow an unconventional path and switch to the modeling of social systems. It takes time to become familiar with social science topics and literature, but it is mandatory to establish serious interdisciplinary connections. During that period, he also had national responsibilities at CNRS, to improve communication of physics. This investment has now started to pay, as shown by recent publications in major interdisciplinary or social science (geography, economics, sociology) journals, including PNAS, J Pub Eco and British J Sociology. His present work takes advantage of the avalanche of social data available on the Web to improve our understanding of society. To achieve this, he collaborate with hard scientists to develop appropriate analysis tools and with social scientists to find relevant questions and interpretations.
His last book : Pourquoi la société ne se laisse pas mettre en équations, Pablo Jensen, Seuil, coll. "Science ouverte", mars 2018
