A Predict model can be scored against its original dataset using the scoring feature in the Predict application. In the workspace select Score a File.
Select the data type that your original dataset is saved as, and using the ellipsis, browse out to the file location the file is saved under.
Then, select whether you want to load a saved Predict modeling file (.vpsm), or select a previously memorized model from your Predict analysis.
Then, start your scoring.
