Shallow decision trees (e.g. few levels) generally do not overfit but have poor performance (high bias, low variance). A decision tree is a widely used supervised learning algorithm in machine learning. It is a flowchart-like structure that helps in making decisions or predictions . The tree consists of internal nodes , which represent features or attributes , and leaf nodes , which represent the possible outcomes or decisions . Decision trees are very interpretable – as long as they are short. The number of terminal nodes increases quickly with depth. The more terminal nodes and the deeper the tree, the more difficult it becomes to understand the decision rules of a tree. A depth of 1 means 2 terminal nodes. Depth of 2 means max. 4 nodes.Back in 2012, Leyla Bilge et al. proposed a wide- and large-scale traditional botnet detection system, and they used various machine learning algorithms, such as …
