Web21 okt. 2024 · Reduction in variance is used when the decision tree works for regression and the output is continuous is nature. The algorithm basically splits the population by using the variance formula. The criteria of splitting are selected only when the variance is reduced to minimum. The variance is calculated by the basic formula WebA decision tree algorithm always tries to maximize the value of information gain, and a node/attribute having the highest information gain is split first. It can be calculated using the below formula: Information Gain= Entropy …
