NettetLinéarisation d'expression faisant intervenir des puissances de sinus. Le calculateur est en mesure de linéariser des expressions de la forme sin n ( x) où n représente un nombre entier. Ainsi pour linéariser l'expression trigonométrique suivante sin 2 ( x), il suffit de saisir linearisation_trigo ( sin ( x) 2). NettetThe linearisation is done case-by-case, that is we take a trained network and linearise in the vicinity of a speci c patient. This results in us knowing the importance of the input variables for that speci c patient.
