It can be a) very expensive b) also very difficult to implement. Video understanding is an active field of research and I'm not sure state of the art is there yet for capturing nuance like engagement potential, categories etc.
State of the art where? College? Silicone Valley? Bangalore? Shanghai? Beijing? Hangzhou?

Re: TikTok reveals details of how its algorithm works
#182TT claims it's a 'key magical ingredient' - and apparently acquisition talks are held up ostensibly over 'access to training data' etc..
But I find this maybe hard to believe.
TT learning is pretty good, but I suspect an algorithm could do it, or possibly some basic ML, not necessarily needed Deep Learning.
I suspect the 'Deep Learning' they use may not even be very sophisticated, but provide cover to radically inflate their ostensible value to CEO acquirers who just love the concept of 'real AI' often irrespective of it's material value.
I'm just suspicious there isn't really much there, and find it odd that an entity like Microsoft would be intimidated by trying to do that piece well.
Re: TikTok reveals details of how its algorithm works
#183I never really understood why TikTok is such a threat Except for maybe collecting too much data, but that’s any app, and luckily Apple is taking their measurements for certain things
This could be very bad for so many reasons.
We need new regs for the new world order.

I've also found that TikTok does a good job of throwing in unexpected videos to test the waters of what the user is interested in. This diversity is one of my favorite things about it.
I wish youtube was better in this regard. The videos it shows me just keep getting more and more focused on what it knows I'm interested in, to the point that it's boring. I discover new things to watch through reddit instead.

The biggest problem in user-facing software right now is that product managers assume they + an algorithm can figure out what you want based on behavior, and that you shouldn't have any direct input in that. The best you'll usually see is an "i don't like this" button. Spotify sidesteps some of this by just giving you a bunch of different algorithms feeding different playlists, so at least there are options, but I mi…
> The biggest problem in user-facing software right now is that product managers assume they + an algorithm can figure out what you want based on behavior Given Tik Tok's success, this appears to be a correct assumption. For every 1 engineer who wants ten different knobs to use the app like a power user, there are 100 or more regular users who don't want anywhere near that much complexity. Catering to the power users…
This isn't happening on social media (except one notable place: interfaces for advertisers), because users there are to be turned into addicts and exploited. With such a design goal, it's reasonable you want to take away user's agency - you want them "engaged" in your "experience", and them having options detracts from that.
I'm serious, by the way, this is not just a "FB/IG/YouTube/TikTok are evil" rant. Their whole design is created around hooking users up. If you wanted to design an efficient, ergonomic app for sharing media content with friends or an audience, these social media platforms are almost the opposite of what you want.

The US never had any such principles. Whenever any country competes with American cash-cows, the US "discovers" a reason to ban them. TikTok is not the first one, see what happened with Bombardier for an example closer to home. Or, when Canada was threatening the US superiority in engine tech, after which the US government threatened to embargo Canada from avionics if they proceeded with the Arrow program. They do th…

By that standard the US also requires IP transfer. Have you already forgotten about PRISM?
>The US has several tech companies with market caps more than double Tik Tok.
Sure, but if China continues in this trajectory then it won't be for long
>Depends if you trust your data with the same government who regularly disappears journalists, I guess.
Depends if you trust your data with the same government who regularly fabricates evidence as an excuse to go and kill a million or so people every once in a while. Or the one that regularly assassinates or threatens to assassinate activists, I guess. The chance of your own government killing you is at least four or five orders of magnitude higher than that of China killing you, same for most other metrics of harm. Can't say the same if you're a foreigner with the US government, though! That being said, US control of the press is much more sophisticated, so there is really no need to kill any American journalists except in exceptional cases. But don't delude yourself, if it ever came to that there would be no hesitation - look at what the USG did to Fred Hampton of Gary Webb, or what they tried to do with Martin Luther King.
>There's evidence Tik Tok has been promoting CCP propaganda. [3]
There's a difference between people on TikTok defending China and TikTok conspiring to push Chinese propaganda. There is evidence for the first one, and absolutely no evidence of the latter. There's people who defend China and push propaganda on Facebook and Instagram too, if you go looking for them. And there's also American propaganda on TikTok.

YouTube's recommendations are arguably just as good as TikTok's in my opinion. The only difference is that YouTube places the burden of choice on you while TikTok makes every choice for you. If you don't quickly find something you'd like to watch on YouTube you're very likely to leave and find something else to entertain you. Meanwhile TikTok is automatically feeding you an infinite source of quick and easy to digest…
I also agree that YouTube's recommendations are pretty good. For example, I like to watch Linux distro reviews which are fairly niche and usually only get a few hundred views but my YouTube homepage is filled with them. In contrast, when I was testing out TikTok it mostly recommended me things with broad appeal like comedy skits and generic science videos that I think 90%+ of the population would find at least somewh…
This is exactly its main weakness. Once it finds one or two things you like, you're hardly ever going to see anything diversity, and if you ever do, it won't be long before that thing completely fills your feed.
I have two Google accounts, and I switch between them for non-YouTube-related reasons. The one is currently all Periodic Videos all the time, the other is all History Matters all the time. It's not as if I lose all interest in chemistry if I switch accounts. If I have a few minutes to kill, I'll end up thinking "History Matters isn't exactly what I want to watch, but I don't want to spend ten minutes trying to find something else", so I watch it, and the algorithm pats itself on the back and cues up another one of the same.

Its the first tech social app i.e. Facebook, MySpace and the like from China, a country that is not America. That is all there is to it. America realizes that China is catching up, and considering there are a billion Chinese, it is inevitable that China will be a foremost power that either competes with or simply overtakes America. The current foremost power, America, doesn't like that. At the very least, this whole…
Why should principles be given to countries that do not reciprocate? All major American tech companies are banished from China, and the only ones left are ones who agreed to transfer IP to be stolen by the CCP.
I don't think Principles are really given. You have principles and you can abide by them.
> All major American tech companies are banished from China
Nope. They aren't banishing anyone. They simply have laws that make it difficult for them to work in China. What law was TikTok not following that they are being forced to sell to a US company? Its essentially extortion.
If the US makes a law, i.e. all foreign-owned companies must store data on US soil or whatever else the issue with TikTok is, then that would actually fit. Rather the administration is forcing Bytedance to sell to a US company i.e. give it to us or we will kill it.
Re: TikTok reveals details of how its algorithm works
#189It's a (seemingly) pretty simple matter of keeping track of how long someone looks at a video, and optimizing to show them videos they'll spend a long time looking at. It's pretty powerful too, I spend much more time looking at TikTok than any other digital content aggregator (to the extent I had to delete it from my phone). They also do some things like sprinkle in random fresh videos, potentially unrelated to your…
It just push the creators to try to keep the viewer the longer by pushing the actual content further and further into their 1 minute.

The answer, of course, is ads. You get more roll time if you hit the 10 min mark, even if its just slightly over
Can someone explain to me why this comment was flagged dead? It's also my understanding that the inflation of video times to certain intervals was driven by how many ads were allowed at a given video length.
