Africa-Press – Gabon. <\/strong> <\/span>Notre cerveau se de\u0301te\u0301riore avec l’exposition excessive de contenus sans inte\u0301re\u0302t, l’intelligence artificielle aussi. C’est la conclusion de chercheurs de l’universite\u0301 du Texas a\u0300 Austin, l’universite\u0301 Purdue et l’universite\u0301 A&M du Texas (E\u0301tats-Unis) dans une e\u0301tude en pre\u0301publication d’octobre 2025. Leur travail fait le paralle\u0300le entre cette de\u0301ficience de l’IA et le brain rot (\u00ab\u00a0pourrissement ce\u0301re\u0301bral\u00a0\u00bb) que subiraient les humains passant trop de temps sur les re\u0301seaux sociaux.<\/p>\n

Pour leur travail, les chercheurs ont constitue\u0301 deux corpus de tweets distincts: courts et viraux d’une part, sensationnalistes de l’autre. Puis ils ont expose\u0301 quatre grands mode\u0300les de langage (LLM) open source a\u0300 des proportions variables de ces donne\u0301es me\u0301lange\u0301es a\u0300 des tweets juge\u0301s plus qualitatifs. Chaque LLM a ensuite subi une se\u0301rie d’e\u0301valuations.<\/p>\n

C’est la diffe\u0301rence entre les re\u0301sultats fournis par l’IA entrai\u0302ne\u0301e avec 100 % de tweets \u00ab\u00a0sains\u00a0\u00bb et ceux issus du me\u0302me algorithme expose\u0301 a\u0300 20, 50 ou 80 % de tweets de faible qualite\u0301 qui te\u0301moigne, selon les chercheurs, d’un de\u0301clin cognitif durable cause\u0301 par les mauvais contenus. L’article de recherche mentionne ainsi une perte de pre\u0301cision non ne\u0301gligeable des mode\u0300les sur les tests de raisonnement ainsi que \u00ab\u00a0des capacite\u0301s nettement moins bonnes pour extraire des informations d’un contexte long \u00ab\u00a0.<\/p>\n

Atteinte par le brain rot, l’IA se met tanto\u0302t a\u0300 sauter des e\u0301tapes dans son plan, tanto\u0302t a\u0300 faire des erreurs de logique, mais surtout a\u0300 re\u0301pondre n’importe comment, sans aucune e\u0301tape dans son raisonnement. Des effets d’autant plus inquie\u0301tants qu’ils persistent apre\u0300s un nouvel entrai\u0302nement sur des donne\u0301es de haute qualite\u0301.<\/p>\n

Circonstance aggravante, les tweets utilise\u0301s pour cette e\u0301tude repre\u0301sentent une faible part de la masse de donne\u0301es avec laquelle ces LLM ont e\u0301te\u0301 entrai\u0302ne\u0301s a\u0300 l’origine. \u00ab\u00a0Nous n’avons utilise\u0301 que 2 millions de tokens (se\u0301quences de caracte\u0300res) sur des mode\u0300les comme Llama3, qui a e\u0301te\u0301 pre\u0301-entrai\u0302ne\u0301 avec 15 milliers de milliards de tokens \u00ab\u00a0, souligne Junyuan Hong, coauteur de l’e\u0301tude en tant que postdoctorant a\u0300 l’universite\u0301 du Texas a\u0300 Austin. Il en conclut qu'\u00a0\u00bbune faible quantite\u0301 de de\u0301chets peut causer des dommages importants et durables \u00ab\u00a0.<\/p>\n

Ve\u0301rifier et filtrer les donne\u0301es d’entrai\u0302nement<\/b><\/p>\n

Interroge\u0301 a\u0300 ce sujet par le magazine Forbes, le chercheur en IA Ilia Shumailov, ancien de Google Deep-Mind, explique que ces re\u0301sultats rejoignent les travaux sur l'\u00a0\u00bbempoisonnement\u00a0\u00bb de l’intelligence artificielle. Soit l’injection malveillante de donne\u0301es dans le corpus d’entrai\u0302nement d’un mode\u0300le afin de modifier son comportement.<\/p>\n

Il affirme toutefois qu’il est difficile d’extrapoler les conclusions de cette e\u0301tude \u00ab\u00a0a\u0300 petite e\u0301chelle \u00a0\u00bb et qui n’a pas encore e\u0301te\u0301 revue par les pairs. Il y voit surtout un rappel de l’importance d’une ve\u0301rification soigneuse des donne\u0301es d’entrai\u0302nement. Les entreprises qui de\u0301veloppent les LLM le font de\u0301ja\u0300, \u00ab\u00a0mais il se peut qu’elles ne filtrent pas assez les donne\u0301es lie\u0301es a\u0300 la viralite\u0301 en ligne \u00ab\u00a0, estime Junyuan Hong.<\/p>\n
