Hi Everyone,
I builded a decision tree model but i couldn't find a entropy scores for each column of the tree.
How can i get that the entropy scores of every variable in the model. i know this informations calculating inside the decision tree alg. but i couldn't find a list of the variable which ordered of the importance and their scores
Can anybody help me ?
There is an information gain node but for entropy itself you'll have to calculate that manually AFAIK. Anyway, I don't think that the decision tree nodes render entropy calculations available for each split. If feature selection for another algorithm is your goal, then consider:
- the R integration, some DT functions report feature importance in a tree;
- the random forest node, which provides you with a less biased assessment of variable importance than a single decision tree.
