La compr\u00e9hension de la diff\u00e9rence entre l’apprentissage supervis\u00e9 et l’apprentissage non supervis\u00e9 est essentielle pour ceux qui s’int\u00e9ressent \u00e0 l’apprentissage machine. Ces deux m\u00e9thodes d’apprentissage sont utilis\u00e9es dans des domaines tels que l’analyse de donn\u00e9es, la reconnaissance de formes, la classification, et bien d’autres applications.<\/p>\n

L’apprentissage supervis\u00e9 est une m\u00e9thode o\u00f9 l’algorithme est entra\u00een\u00e9 sur un ensemble de donn\u00e9es \u00e9tiquet\u00e9es. Cela signifie que les donn\u00e9es d’entr\u00e9e sont associ\u00e9es \u00e0 des \u00e9tiquettes ou des r\u00e9sultats connus, ce qui permet \u00e0 l’algorithme d’apprendre \u00e0 pr\u00e9dire ou \u00e0 cat\u00e9goriser de nouvelles donn\u00e9es en fonction de ses connaissances pr\u00e9alablement acquises. Les techniques courantes d’apprentissage supervis\u00e9 comprennent la r\u00e9gression lin\u00e9aire, la r\u00e9gression logistique, les machines \u00e0 vecteurs de support (SVM), et les r\u00e9seaux de neurones.<\/p>\n

D’autre part, l’apprentissage non supervis\u00e9 consiste \u00e0 utiliser un ensemble de donn\u00e9es non \u00e9tiquet\u00e9es et \u00e0 permettre \u00e0 l’algorithme d’explorer les structures et relations intrins\u00e8ques des donn\u00e9es. Il cherche \u00e0 d\u00e9couvrir des sch\u00e9mas ou des regroupements non \u00e9tiquet\u00e9s, et il est souvent utilis\u00e9 dans des t\u00e2ches telles que la classification automatique, la segmentation d’image, et la recommandation de contenu. Les m\u00e9thodes d’apprentissage non supervis\u00e9 comprennent la classification hi\u00e9rarchique, le clustering k-means, les r\u00e9seaux de neurones non supervis\u00e9s, et l’analyse en composantes principales (PCA).<\/p>\n
