Abstract
In an embodiment, a computer-implemented method for training a decision tree using a database system, the decision tree comprising a plurality nodes, comprises, by one or more computing devices: storing in a database input data for training the decision tree, the input data comprising a plurality of feature values corresponding to a plurality of features; generating a particular node of the plurality of decision nodes by: selecting a subset of the plurality of features and a subset of the input data; using one or more queries to the database system, for each feature of the subset of the plurality of features, calculating a variance value associated with the feature based on the subset of the input data; identifying a particular feature of the subset of the plurality of features associated with the highest variance value; associating the particular node with the particular feature, wherein the particular node causes the decision tree to branch based on the particular feature.
