Witryna1.5566567074628228. The gini impurity index is defined as follows: Gini ( x) := 1 − ∑ i = 1 ℓ P ( t = i) 2. The idea with Gini index is the same as in entropy in the sense that the more heterogenous and impure a feature is, the higher the Gini index. A nice property of the Gini index is that it is always between 0 and 1, and this may make ... WitrynaOccupational Exposure Limit (OEL) residual solvent elemental impurities (by establishing PDE).
