Ranking Factorization Recommender

User 2919 | 12/29/2015, 6:04:45 AM

I am using the itemdata feature apart from the itemid and userid features in the ranking factorization recommender system. The entire process runs (viz the adaptive SGD) and the model works fine for recommend() method. However, when I try to export the getsimilar_items() output to a CSV, the CSV is always empty. Please let me know how to resolve the issue as soon as possible.

Can you share the code snippet that you use to generate the similar items?
