Description

Dans les arbres, on filtre les les arbres de profondeur 1, inutiles car redondants avec l'analyse univariée.
Il faudrait étendre ce filtrage aux arbres n'utilisant qu'une seule variable, même si l'arbre est de prodondeur supérieure à 1 (cas d'une variable coupée de façon binaires plusieurs fois).
Exemple: premier arbre de régression dans LearningTest\TestKhiops\DTRegression\Iris, avec un arbre de prodondeur 2 n'utilisant que la variable Class.
