WebMay 18, 2024 · A Decision Tree is a supervised learning predictive model that uses a set of binary rules to calculate a target value. It can be used both for regression as well as classification tasks. Decision trees have three main parts: Root Node: The node that performs the first split. Terminal Nodes/Leaf node: Nodes that predict the outcome. WebLightGBM adds nodes to trees based on the gain from adding that node, regardless of depth. This figure from the feature documentation illustrates the process. Because of this growth strategy, it isn’t straightforward to use max_depth alone to limit the complexity of …
