Is HybridRecommender.R missing some commands #25

Closed jackyrx closed 5 years ago

jackyrx commented 5 years ago

Since I have read through Hybrid Recommender.R , and I saw there is missing the below in order to set the HYBRID as the recommender entry.

recommenderRegistry$set_entry(
  method="HYBRID", dataType = "realRatingMatrix", fun= HybridRecommender,
  description="Hybrid Recommender")

Also, besides this issue, is the HybridRecommender only performs prediction (both rating and TopNList) and only able to evaluate the ratings only? Is any chance/ plan that extending that to evaluation on topNList (ROC confusion matrix)?

Thank you.

HybridRecommender is actually not a recommender algorithm, but just a wrapper that contains recommender algorithms. So it is similar to the function Recommender and that is why it is not in the registry.

About the prediction: Can you add some code I can run that shows the problem?

This is now resolved. See ? HybridRecommender.
