WebJan 10, 2024 · Prerequisites: Decision Tree, DecisionTreeClassifier, sklearn, numpy, pandas Decision Tree is one of the most powerful and popular algorithm. Decision-tree algorithm falls under the category of supervised learning algorithms. It works for both continuous as well as categorical output variables. WebA decision tree is a supervised learning approach wherein we train the data present knowing the target variable. As the name suggests, this algorithm has a tree type of structure. Let us first look into the decision tree’s theoretical aspect and then look into the same graphical approach.
