Lenskit: How to run LensKit recommender and evaluator from java

Question

I have a maven project in which I have a java file that pre-processes the data and creates a number of new data files that would like to be the input files in the Lenskit. When the evaluator finishes the evaluation of each file, I would like to get the result values (RMSE etc) back in my java code to continue with my kind of analysis. So, I guess that somehow I need to call the evaluator process each time a new data input file is generated and take the RMSE and other metrics values as output. Does anybody know how could I possibly do that?

Answer 1

The SimpleEvaluator exists for that very purpose.
