'''Slow feature analysis (SFA)''' is an unsupervised learning algorithm for extracting slowly varying features from a quickly varying input signal. It has been successfully applied, e.g., to the self-organization of complex-cell receptive fields, the recognition of whole objects invariant to spatial transformations, the self-organization of place-cells, extraction of driving forces, and to nonlinear blind source separation. | '''Slow feature analysis (SFA)''' is an unsupervised learning algorithm for extracting slowly varying features from a quickly varying input signal.

Définition
L'analyse des caractéristiques lentes est un modèle linéaire factoriel qui utilise l'information de signaux temporels pour apprendre des caractéristiques invariantes ( Wiskott et Sejnowski, 2002 ).
