This node uses the spark.ml logistic regression implementation to train a logistic regression model in Spark, supporting different regularization options. The target column must be nominal, whereas the feature columns can be either nominal or numerical.

Use the Spark Predictor (Classification) node to apply the learned model to unseen data.

Please refer to the Spark documentation for a full description of the underlying algorithm.

This node requires at least Apache Spark 2.4.
