L’apprentissage non supervis\u00e9 est une branche de l’intelligence artificielle qui a gagn\u00e9 en popularit\u00e9 ces derni\u00e8res ann\u00e9es. Cette m\u00e9thode d’apprentissage permet \u00e0 un algorithme d’analyser des donn\u00e9es sans la pr\u00e9sence d’un superviseur humain, contrairement \u00e0 l’apprentissage supervis\u00e9 o\u00f9 l’algorithme est entrain\u00e9 \u00e0 reconna\u00eetre des patterns \u00e0 partir de donn\u00e9es \u00e9tiquet\u00e9es. Les techniques avanc\u00e9es d’apprentissage non supervis\u00e9 ont ouvert de nouvelles possibilit\u00e9s dans de nombreux domaines, y compris l’analyse de donn\u00e9es, la reconnaissance de formes, et bien d’autres.<\/p>\n

Qu’est-ce que l’apprentissage non supervis\u00e9?<\/p>\n

L’apprentissage non supervis\u00e9 implique l’utilisation d’algorithmes pour trouver des structures ou des patterns dans des ensembles de donn\u00e9es non \u00e9tiquet\u00e9es. Il s’agit essentiellement de permettre \u00e0 l’algorithme d’identifier les corr\u00e9lations, les similarit\u00e9s et les diff\u00e9rences entre les diff\u00e9rentes donn\u00e9es sans qu’un superviseur ne l’indique explicitement. Cela le rend particuli\u00e8rement adapt\u00e9 \u00e0 la d\u00e9couverte de tendances et de mod\u00e8les subtils qui seraient difficiles \u00e0 d\u00e9tecter par d’autres moyens.<\/p>\n

Techniques avanc\u00e9es d’apprentissage non supervis\u00e9<\/p>\n

Il existe plusieurs techniques avanc\u00e9es d’apprentissage non supervis\u00e9, parmi lesquelles le clustering, l’analyse en composantes principales (PCA) et les autoencodeurs. Le clustering consiste \u00e0 regrouper des \u00e9l\u00e9ments similaires en fonction de leurs caract\u00e9ristiques communes, tandis que l’analyse en composantes principales est utilis\u00e9e pour r\u00e9duire la dimensionnalit\u00e9 des donn\u00e9es en conservant le maximum d’information possible. Les autoencodeurs, quant \u00e0 eux, sont des r\u00e9seaux de neurones utilis\u00e9s pour apprendre \u00e0 reconstruire les donn\u00e9es en minimisant la perte d’information.<\/p>\n
