![]() On some case algorithm C4.5 only solved with calculating information gain, especially in discrete data settlement or categorical and for mixed data, solution will more details _ that is with look for Gain Ratio value. And also can count with Here 's a different index with the gain ratio. ![]() Different with C4.5 algorithm that can count until stage gain ratio even the C4.5 algorithm also works count only with information gain. ![]() In example ID3 calculation will finished at stage calculate information gain. of several algorithm the base from the calculation permanent same that is look for Entropy value as Step early, however for step next will different stages in accordance of each criterion in the algorithm that. Basically _ split decision tree algorithm Becomes a number of part, that is there is CART, ID3, C4.5, C5.0, Random Forest, and Gradient Boosting algorithms. ![]()
