I was searching some information on what are the principles behind the TikTok algorithm/recommendation engine and I found this very recent preprint. I wanted to have some opinions on its validity.
It's probably valid but on a quick reading I don't see a lot of depth or a clear understanding of "what the magic is".
Yeah, I pretty much understood some of it because it is very clear. I was researching some explanation or first-principles approach to the TikTok algorithm but going through ResearchGate/Arxiv but found few technical reports and the best one was this one (and very recent).
And going through Google is a mine-field because of marketing companies SEO bombing the words "Tiktok" and "algorithm"
