You can if you want but we have external tools for the UR that are much
more flexible. The UR has tuning that can’t really be covered by the built
in API. They do MAP@k as well
as creating a bunch of other metrics and comparing different types of input
data. They use a running UR to make queries against.

Subject:  UR evaluation

hi all, i successfully trained a universal recommender but i don't know how
to evaluate the model.

Is there a recommended way to do that?
I saw that *predictionio-template-recommender* actually has
the Evaluation.scala file which uses the class *PrecisionAtK *for the
Should i use this template to implement a similar evaluation for the UR?
