Gradient Boosting - A Concise Introduction from Scratch
Gradient boosting is a machine learning technique used in regression and classification tasks, among others. It gives a prediction model in the form of an ensemble of weak prediction models, which are typically decision trees. When a decision tree is the weak learner, the resulting algorithm is called gradient-boosted trees; it usually outperforms random forest. A gradient-boosted trees … WebApr 11, 2024 · Tree-based methods are a family of machine learning algorithms that use a tree-like structure to split the data into smaller and more homogeneous groups based on certain features or rules. WebLightGBM, short for light gradient-boosting machine, is a free and open-source distributed gradient-boosting framework for machine learning, originally developed by Microsoft. [4] [5] It is based on decision tree algorithms and used for ranking, classification and other machine learning tasks. chinese needles therapy
