A decision tree is a tree-like model that acts as a decision support tool, visually displaying decisions and their potential outcomes, consequences, and costs. From there, the “branches” can easily be evaluated and compared in order to select the best courses of action.
What is decision tree in software engineering?
A Decision Tree offers a graphic read of the processing logic concerned in a higher cognitive process and therefore the corresponding actions are taken. The perimeters of a choice tree represent conditions and therefore the leaf nodes represent the actions to be performed looking at the result of testing the condition.

How do you avoid overfitting in decision trees?
Two approaches to avoiding overfitting are distinguished: pre-pruning (generating a tree with fewer branches than would otherwise be the case) and post-pruning (generating a tree in full and then removing parts of it). Results are given for pre-pruning using either a size or a maximum depth cutoff.
