> Btw, I could imagine us wanting to change this later. If we're
recommending items a user could add to their basket, then we might want to
suggest the most frequent item rather than nothing.
Do we need to support this now? That may not be expected for all the
scenarios. And it seems an Imputer can help with the issue.
