Le CERN apporte son expertise en physique fondamentale, en donn\u00e9es scientifiques et en calcul \u00e0 grande \u00e9chelle, tandis que Mistral AI contribue avec l&rsquo;entra\u00eenement de mod\u00e8les \u00e0 grande \u00e9chelle. L&rsquo;accent est d&rsquo;abord mis sur la physique des hautes \u00e9nergies, mais ces travaux pourraient aussi nourrir les approches d&rsquo;IA de l&rsquo;ensemble de la communaut\u00e9 scientifique.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Un mod\u00e8le de fondation pour la physique des collisionneurs<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">L&rsquo;objectif central est un mod\u00e8le unique pr\u00e9-entra\u00een\u00e9, pr\u00e9sent\u00e9 comme le premier mod\u00e8le de fondation pour la physique des collisionneurs : un \u00ab Large Physics Model \u00bb. Il serait entra\u00een\u00e9 sur des milliards de collisions proton-proton simul\u00e9es du Grand collisionneur de hadrons (LHC) et prendrait en charge plusieurs t\u00e2ches, dont la reconstruction des collisions de particules, l&rsquo;identification des particules, la d\u00e9tection de signaux inattendus et l&rsquo;\u00e9valuation de futurs concepts de d\u00e9tecteurs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Aujourd&rsquo;hui, la reconstruction repose sur une cha\u00eene d&rsquo;algorithmes sp\u00e9cialis\u00e9s qui convertissent progressivement les signaux des d\u00e9tecteurs en objets physiques. L&rsquo;apprentissage automatique am\u00e9liore d\u00e9j\u00e0 certaines \u00e9tapes de cette cha\u00eene, et un mod\u00e8le de fondation pourrait apprendre sur l&rsquo;ensemble de la cha\u00eene au sein d&rsquo;un seul mod\u00e8le.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Les volumes de donn\u00e9es en jeu sont consid\u00e9rables. Le CERN a stock\u00e9 \u00e0 ce jour environ un exaoctet (un million de t\u00e9raoctets) de donn\u00e9es exp\u00e9rimentales du LHC, et le LHC \u00e0 haute luminosit\u00e9 (HL-LHC), dont la mise en service est attendue vers 2030, multipliera par dix le nombre de collisions.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Des capacit\u00e9s d&rsquo;IA partag\u00e9es pour la physique<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Enrica Porcari, directrice de l&rsquo;informatique du CERN, estime que la physique des hautes \u00e9nergies offre \u00ab un environnement unique dans lequel l&rsquo;intelligence artificielle peut \u00eatre d\u00e9velopp\u00e9e et test\u00e9e \u00bb avec rigueur, et que le partenariat vise \u00e0 cr\u00e9er des capacit\u00e9s d&rsquo;IA que l&rsquo;ensemble de la communaut\u00e9 de la physique pourra partager. Johannes Brandstetter, vice-pr\u00e9sident de l&rsquo;IA pour l&rsquo;ing\u00e9nierie chez Mistral AI, se dit fier de travailler avec le CERN pour explorer ce que les mod\u00e8les d&rsquo;IA \u00e0 grande \u00e9chelle peuvent apporter \u00e0 la physique des particules, avec \u00e0 la cl\u00e9 de possibles d\u00e9couvertes scientifiques.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Le CERN et le d\u00e9veloppeur d&rsquo;IA Mistral AI ont sign\u00e9 une d\u00e9claration d&rsquo;intention pour un partenariat strat\u00e9gique de long terme sur les mod\u00e8les de fondation au service de la d\u00e9couverte scientifique.
