I would like to use universal recommender and in my case I would to use one primary event "like" and a secondary event "view".
On my website, "like" event will be send when a user will click on a like button of the UI, whereas the secondary event "view" will be send for each page view.
So It's possible that a user will not have primary events but a lots of secondary events. It is correct to do this ? All users will get recommendation is this case ?
