Article Introduction：Tree-based algorithms are a type of machine learning algorithm based on tree structures, including decision trees, random forests, and gradient boosting trees. These algorithms perform prediction and classification by building a tree structure, gradually segmenting the input data into different subsets, and finally generating a tree structure to represent the relationship between the features and labels of the data. This algorithm has intuitive interpretability and good robustness, and has good performance for problems with data with discrete characteristics and nonlinear relationships. Tree-based algorithms simplify model complexity by automatically selecting the most influential features by considering their importance and interrelationships. In addition, tree-based algorithms can also handle missing data and outliers, making the model more robust. In short, tree-based algorithms have wide application in practical applications.
