The original algorithms rely solely on spectral information and do not use spatial information; this usage is normally justified in subpixel target detection, since the target size is smaller than the size of a pixel. However... the background(and the false alarms) may be spatially correlated and the point spread function can distribute the energy of a point target between several neighboring pixels, the implementation of spatial filtering algorithms considerably improved target detection. 2, record 1, English, - beamforming%20algorithm

La classification élastique est un mécanisme qui a été conçu [...] en milieu hiérarchique. Étant donné un problème cible et une hiérarchie de concepts représentant des problèmes, la classification élastique permet de mettre en évidence des chemins de similarité entre problèmes (concepts) de la hiérarchie et le problème cible. La classification élastique est un mécanisme de remémoration guidée par l'adaptabilité : les solutions des problèmes remémorés sont nécessairement adaptables. La classification élastique peut être considérée comme une extension de la classification hiérarchique floue. 2, record 2, French, - classification%20%C3%A9lastique
