Decision trees serve various purposes in machine learning, including classification, regression, feature selection, anomaly detection, and reinforcement learning. They operate using straightforward if-else statements until the tree’s depth is reached. Grasping … 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 a sort of supervised machine learning where the training data is continually segmented based on a particular parameter, describing the input and the associated output. Decision nodes and leaves are the two components that can be used to explain the tree. The choices or results are represented by the leaves.
