Magika peut identifier avec pr\u00e9cision les langages de programmation utilis\u00e9s dans le contenu, les m\u00e9thodes de compression, les packages d'installation, le code ex\u00e9cutable, les types de balisage, les formats audio, vid\u00e9o, de documents et d'images.

Le mod\u00e8le a \u00e9t\u00e9 form\u00e9 en utilisant le framework Keras sur 25 millions d'exemples de fichiers et prend en charge la reconnaissance de 116 types de donn\u00e9es avec une pr\u00e9cision d'au moins 99%. Le mod\u00e8le est empaquet\u00e9 au format ONNX et a une taille d'\u00e0 peine 1 Mo. L'utilisation de m\u00e9thodes d'apprentissage automatique profond a permis d'am\u00e9liorer la pr\u00e9cision de d\u00e9tection de 50% par rapport au syst\u00e8me pr\u00e9c\u00e9demment utilis\u00e9 par Google bas\u00e9 sur des r\u00e8gles d\u00e9finies manuellement.    <center><img decoding=\"async\" alt=\"Google a ouvert le code du syst\u00e8me IA Magika pour d\u00e9terminer le type de contenu des fichiers\" src=\"\/wp-content\/uploads\/2024\/02\/a29b2b04dbac4eeccf3c1a05c78a394a.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>      <\/p>\n<p>Dans Google, le syst\u00e8me est utilis\u00e9 pour classifier les fichiers dans les services Gmail, Drive, Code Insight et Safe Browsing lors des v\u00e9rifications de s\u00e9curit\u00e9 et de conformit\u00e9 aux r\u00e8gles des services.

La configuration d\u00e9ploy\u00e9e dans l'infrastructure de Google permet de scanner plusieurs millions de fichiers par seconde et plusieurs centaines de milliards de fichiers par semaine. Apr\u00e8s le chargement du mod\u00e8le, le temps de formation de la sortie est de 5 \u00e0 6 ms lors des tests sur un c\u0153ur CPU.

L'interface en ligne de commande et l'API prennent en charge l'ex\u00e9cution d'op\u00e9rations en mode batch, c'est-\u00e0-dire qu'elles permettent de v\u00e9rifier plusieurs fichiers en une seule requ\u00eate. Il existe un mode de scan r\u00e9cursif de tout le contenu d'un r\u00e9pertoire et trois modes de pr\u00e9diction pour ajuster la robustesse aux erreurs (forte confiance, confiance moyenne et meilleure supposition).             <center><img decoding=\"async\" alt=\"Google a ouvert le code du syst\u00e8me IA Magika pour d\u00e9terminer le type de contenu des fichiers\" src=\"\/wp-content\/uploads\/2024\/02\/bbcccfb5c16608a5765ecd0e51fcade2.png\" style=\"display:block;margin: 0 auto;\" \/><\/center><br \/>\n<br \/>Source : <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=60611\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f Google \u043e\u0431\u044a\u044f\u0432\u0438\u043b\u0430 \u043e\u0431 \u043e\u0442\u043a\u0440\u044b\u0442\u0438\u0438 \u043a\u043e\u0434\u0430 \u043f\u0440\u043e\u0435\u043a\u0442\u0430 Magika, \u043f\u0440\u0435\u0434\u043d\u0430\u0437\u043d\u0430\u0447\u0435\u043d\u043d\u043e\u0433\u043e \u0434\u043b\u044f \u043e\u043f\u0440\u0435\u0434\u0435\u043b\u0435\u043d\u0438\u044f \u0442\u0438\u043f\u0430 \u0441\u043e\u0434\u0435\u0440\u0436\u0438\u043c\u043e\u0433\u043e \u043d\u0430 \u043e\u0441\u043d\u043e\u0432\u0435 \u0430\u043d\u0430\u043b\u0438\u0437\u0430 \u0438\u043c\u0435\u044e\u0449\u0438\u0445\u0441\u044f \u0432 \u0444\u0430\u0439\u043b\u0435 \u0434\u0430\u043d\u043d\u044b\u0445.
