ML Gini Impurity and Entropy in Decision Tree
Witryna28 mar 2024 · The examples of pentavalent impurities are Phosphorus (P), Arsenic (As), Antimony (Sb). The pentavalent impurity is added in a very minute fraction in the N-type semiconductor such that the crystal structure of the original intrinsic semiconductor is not disturbed. Witryna2 lis 2024 · This is termed the purity of the node. For example, Not Working has 5 Pass and 1 Fail, hence it is purer than the Working node which has 5P and 4F. A leaf node would be one which contains either Pass or Fail class only. A node which is impure can be branched further for improving purity. howell jones llp
