I guess that my question is really just on how server-side information gained from users is maintained.
Assuming that my current Roon account is the same as previous installations, will my recommendations made by Valence take into account my past favourite albums and tracks from my older and now lost (to me) ‘activity’?
Various circumstances have meant that I haven’t been able to keep a backup of past databases, but Roon obviously has collected the data about my favourite albums and tracks from past installs, which drove recommendations for me and collectively for other users.
With any new install (without database backup), will the recommendation engine take into account my old favourites when personalising my recommendations? Or are recommendations reset to the data from the whole community?
From the recommendations I am seeing I think it is the latter, and without knowing how Roon preserves user anonymity from usage data, I think it makes sense that Roon is using some client-side processing of favourites to drive what Valence suggests - even if it is just flagging active, over past, installations.
