No but we have 2 ways to handle this situation automatically and you can tell if recommendations are not from personal user history.
1. when there is not enough user history to recommend, we fill in the lower ranking recommendations with popular, trending, or hot items. Not completely irrelevant but certainly not as good as if we had more data for them. 2. You can also mix item and user-based recs. So if you have an item, perhaps from the page or screen the user is looking at, you can send both user and item in the query. If you want user-based, boost it higher with the userBias. Then is the query cannot send back user-based it will fill in with item-based. This only works in certain situations where you have some example item. As always if you do a user-based query and all scores are 0, you know that no real recommendations are included and can take some other action.

For example the user with 2 view events usually get unrelevant recommendations, but 5 events would be enough. Thanks! Regads, Adam Krajcs
