Recommending for new products
Hello,
I am sort of confused on how PIO handles the recommendations for products that were not in our training.
I understand for handling new users, it recommends the most popular products

PredictionIO is not a recommender. It is a Framework you add templates to. The templates do all the machine learning and can be of many types.
That said if you are using the Universal Recommender here: https://github.com/actionml/universal-recommender <https://github.com/actionml/universal-recommender> the user’s actions in real-time are used to make recommendations—no need to have them in training.
However any item to be recommended must be known at `pio train` time. If you have some items that have no events you should provide another method for getting events. Think of Recommenders as part of discovery, which usually includes browsing by category or other property, search, and recommend. Both browse and search will allow users to find items without events and in doing so create events for them.
The Universal Recommender adds random recs and the ability to boost items by properties and so can recommend when the are no events associated with items. This should not replace browse or search but can be of some help with new items.
