WitrynaIf None, then nodes are expanded until all leaves are pure or until all leaves contain less than min_samples_split samples. If int, values must be in the range [1, inf). min_impurity_decrease float, default=0.0. A node will be split if this split induces a decrease of the impurity greater than or equal to this value. Values must be in the … Witrynaf(p) = p(1 −p). We then use that split with maximal impurity reduction ∆I= p(A)I(A) −p(A L)I(A L) −p(A R)I(A R) The two impurity functions are plotted in figure (2), along with a rescaled version of the Gini measure. For the two class problem the measures differ only slightly, and will nearly always choose the same split point.
