I have a Random forest model for which I am trying to get the featureImportance vector.
Map<Object,Object> categoricalFeaturesParam = new HashMap<>(); scala.collection.immutable.Map<Object,Object> categoricalFeatures = (scala.collection.immutable.Map<Object,Object>) scala.collection.immutable.Map$.MODULE$.apply(JavaConversions.mapAsScalaMap(categoricalFeaturesParam).toSeq()); int numberOfClasses =2; RandomForestClassifier rfc = new RandomForestClassifier(); RandomForestClassificationModel rfm = RandomForestClassificationModel.fromOld(model, rfc, categoricalFeatures, numberOfClasses); System.out.println(rfm.featureImportances()); When I run above code I found featureImportance as null. Do I need to set anything in specific to get the feature importance for the random forest model. Thanks, Rachana
