A form of learning from examples in which a set of examples are investigated for similarities and dissimilarities from which to make generalizations.

CONT

L'apprentissage inductif se divise en deux sous-domaines. Le premier sous-domaine est l'apprentissage des similarités (Similarity-Based Learning, SBL) dont le but est de collecter les propriétés communes à un ensemble d'exemples d'un concept, et absentes de l'ensemble des contre-exemples à ce concept. Le deuxième sous-domaine est la classification symbolique.

CONT

Si la base de connaissances est plus pauvre en information, on prend une nouvelle hypothèse de travail : ce sont les ressemblances et différences observées entre les instances qui caractérisent justement le concept à définir. On parle alors d'apprentissage par recherche de similarités (Similarity Based Learning), et le principal mécanisme d'inférence utilisé est la généralisation.
