    Methods in org.apache.ignite.ml.tree that return DecisionTreeModel
    Modifier and Type | Method and Description
    --- | ---
    `static DecisionTreeModel` | NodeData.`buildDecisionTreeModel(Map<Integer,NodeData> nodes)` Builds the DT model by the given sorted map of nodes.
    `<K,V> DecisionTreeModel` | DecisionTreeTrainer.`fit(Dataset<EmptyContext,DecisionTreeData> dataset)`
    `<K,V> DecisionTreeModel` | DecisionTreeTrainer.`fitWithInitializedDeployingContext(DatasetBuilder<K,V> datasetBuilder, Preprocessor<K,V> preprocessor)` Trains model based on the specified data.
    `static DecisionTreeModel` | DecisionTreeModel.`fromJSON(Path path)` Loads DecisionTreeModel from JSON file.
    `protected <K,V> DecisionTreeModel` | DecisionTreeTrainer.`updateModel(DecisionTreeModel mdl, DatasetBuilder<K,V> datasetBuilder, Preprocessor<K,V> preprocessor)` Trains new model based on dataset because there is no valid approach to update decision trees.
