The paper you link does not describe YouTube's algorithm. YouTube's selection algorithm is proprietary and not revealed to the public. You just linked a paper from researchers at Google studying the topic of video recommendation. The extent to which it describes youtube's actual algorithm is not at all obvious.

Some researchers at tiktok's parent company released a paper on a recommender system called Monolith here: https://arxiv.org/abs/2209.07663.

I'm not sure its actually what tiktok is using, but they do say that "Monolith has successfully landed in the BytePlus Recommend product".

Also interested been looking into this myself. Some materials of potential interest:

Official TikTok blog post describing with very limited detail how it works: How TikTok recommends videos #ForYou

Papers:

WSJ did a video on them trying to reverse engineer the algorithm, not too technical though Investigation: How TikTok's Algorithm Figures Out Your Deepest Desires

Some blogs I came across that may or may not be reliable:

Typically, large companies don't use a single model, but rather a large number of different models, all performing different tasks (recommending, filtering, etc). It would very difficult to describe the complete recommendations pipeline (i.e from user request to final candidate) in a single academic paper.

Whatever you can read are outdated. They don't reveal what they actually use. They are rumored to have the best recommendation system.

There is the claim that any system can be (approximately) reverse engineered if one has access to the results of the system. Are those too hidden from the public?

What is "best" is subjective. At least I was reading last week that any moderate fitness related interest brings quite unhealthy content very quickly. But it has to be better than Amazon's system, anyway.
