Step3: Predicting the Results - University of Connecticut We retrieved the original labels from the column of predicted indices with IndexToString. Then, we used Pipeline to chain these three procedures: Indexers -> Random Forest -> Label Converter. And we fitted the dataframe train and used dataframe test to test the model. Finally, we printed out the accuracy rate.
