WebDec 22, 2024 · This projection from a 2D space onto a line is reducing the dimensionality of the data, this is LDA. LDA uses Fisher’s linear discriminant to reduce the dimensionality of the data whilst maximizing the separation between classes. It does this by maximizing the distance between means and minimizing within-class variance. PCA vs LDA WebIntroduction à la représentation ou la projection de Fischer à partir d’une molécule tridimensionnelle simple sur un plan. Exemple des étapes à réaliser afin de représenter …
