I don’t know what ANN is but your comment raises two questions in my mind -

1. Where did your first vector of [0.99, 0.3, 0.7] come from? You later present the concept of user vectors which are vectors for different cohorts of users but don’t name the first vector as a user vector.

2. I feel my example of vectors for “general population users” and “bible literalist blogger” user aligns with your “user vector” concept.
