td-decision-forest

You can build a decision forest classification model in Teradata Vantage by using an automated workflow that handles data preprocessing, model training with the TD_DecisionForest function, prediction, and performance evaluation.

Yes, you need Teradata Vantage with ClearScape Analytics enabled and appropriate database permissions to execute the automated decision forest creation, prediction, and evaluation workflows.

Yes, the automated workflow handles missing values, feature scaling, and encoding directly within Teradata Vantage before training the decision forest model to predict customer churn.

The best way to evaluate decision forest models deployed on a database is to use automated workflows that generate predictions and provide comprehensive performance metrics directly within Teradata Vantage.

Yes, the TD_DecisionForest function workflow supports complete analytical processes including feature engineering and data scaling before executing the model training phase.

Classification predictions may lack historical drivers if data preprocessing steps like missing value handling and feature encoding are skipped before deploying the decision forest model.
