La qualit\u00e9 des donn\u00e9es influe directement sur la pr\u00e9cision des pr\u00e9dictions ; il est donc indispensable de s\u00e9lectionner des sources fiables et de garantir l'int\u00e9grit\u00e9 des informations.<\/p>\n<\/li>\n<li>\n<p dir=\"ltr\"><strong>Pr\u00e9traitement des donn\u00e9es : <\/strong>Avant d'appliquer des algorithmes pr\u00e9dictifs, il est n\u00e9cessaire de nettoyer et d'organiser les donn\u00e9es.
