I wonder, why predicted features URIs should be dataset dependent, rather than model dependent ? Semantically, the same variable is predicted by a given model, regardless of which dataset is submitted for the model. Dataset dependent URIs for predicted variables may introduce confusion if somebody stores triples from several datasets in a same triple storage (which is at the end the intended use of all the RDF serialization).

In case of models , the features are relative to the model , e.g. /model/1/predicted have the same policy as /model/1 .
