The Bagged Trees output contains variable usage statistics<\/strong><\/p>\n<p>Bagged trees is a machine learning technique that uses a collection of decision trees to make predictions. Each tree in the collection is trained on a different subset of the data, and the predictions from the individual trees are then combined to make a final prediction. This technique can be used to improve the accuracy of predictions, especially when the data is noisy or when there is a lot of variation in the data.<\/p>\n<p>The output of a bagged trees model contains information about how each variable was used by the trees in the collection.
