Witryna28 lis 2024 · The impurity reduction of a test d on a tree node S is defined as d (S,d) = h (S) - h (S \mid d). A test that causes larger impurity reduction is considered more discriminative. Based on the concavity property of h, it is easy to show that d (S,d)\ge 0 for any tree node S and test d. Witryna6 sie 2011 · Impurity reduction can lead to an increase in the volume fraction of fine recrystallized grains, as observed in Fig. 5. Besides refining grains, recrystallization plays an important role in eliminating strain hardening and releasing accumulated energy. Witrynaimpurity.
