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 metrics. Should i use this template to implement a similar evaluation for the UR? thanks, Marco Goldin Horizons Unlimited s.r.l.
