Decision Tree in Data Mining Application Importance ...

Dec 18, 2019  Algorithm of Decision Tree in Data Mining. A 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.

Data Mining - Decision Tree Induction - Tutorialspoint

Data Mining - Decision Tree Induction. A decision tree is a structure that includes a root node, branches, and leaf nodes. Each internal node denotes a test on an attribute, each branch denotes the outcome of a test, and each leaf node holds a class label. The topmost node in the tree is the root node.
