Import decision tree regressor python
Witryna7 gru 2024 · Let’s look at some of the decision trees in Python. 1. Iterative Dichotomiser 3 (ID3) This algorithm is used for selecting the splitting by calculating information gain. Information gain for each level of the tree is calculated recursively. 2. C4.5. This algorithm is the modification of the ID3 algorithm.
