DEPRECATED. Use PersistentModel instead.
(Since version 0.9.2) Use PersistentModel instead.
Save the model to some persistent storage.
This method should return true if the model has been saved successfully so
that PredictionIO knows that it can be restored later during deployment.
This method should return false if the model cannot be saved (or should
not be saved due to configuration) so that PredictionIO will re-train the
model during deployment. All arguments of this method are provided by
automatically by PredictionIO.
ID of the run that trained this model.
Algorithm parameters that were used to train this model.
