Witryna13 kwi 2024 · Gini impurity and information entropy. Trees are constructed via recursive binary splitting of the feature space. In classification scenarios that we will be discussing today, the criteria typically used to decide which feature to split on are the Gini index and information entropy. Both of these measures are pretty similar numerically. WitrynaThe list criteria provide the mechanism for evaluating harm for all substances by weighing information from the other agencies ...
