Gradient boosted trees with extrapolation
WebApr 10, 2024 · Gradient Boosting Machines. Gradient boosting machines (GBMs) are another ensemble method that combines weak learners, typically decision trees, in a sequential manner to improve prediction accuracy. Webspark.gbt fits a Gradient Boosted Tree Regression model or Classification model on a SparkDataFrame. Users can call summary to get a summary of the fitted Gradient Boosted Tree model, predict to make predictions on new data, and write.ml / read.ml to save/load fitted models. For more details, see GBT Regression and GBT Classification.

Decision trees evaluate an input based on conditions at each node, which are determined through model training. They can be thought of as a nested if-else statement or as a piecewise function.
WebWe propose Instance-Based Uncertainty estimation for Gradient-boosted regression trees (IBUG), a simple method for extending any GBRT point predictor to produce probabilistic predictions. IBUG computes a non-parametric distribution around a prediction using the k k -nearest training instances, where distance is measured with a tree-ensemble kernel.
