'''Slow feature analysis '''


'''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.

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 ).
