same as it’s legal to use open source licensed software to profit. a lot of academics don’t care, and their work might be built very strongly on other work. there might or might not be a patent on this research, but I would guess probably not?

I thought github projects were only ok to use if the author provided a LICENSE file e.g. MIT or APACHE 2.0 , do these papers include a license clause at the bottom? Usually no right , so it seems to be a ‘grey’ area

well, is it legal to do a "clean-room" implementation from the descriptions in the papers themselves, without looking at any provided code?

(this should almost always be feasible, and is commonly done for non-IP-related reasons e.g. someone might make a PyTorch version of something when the original version was done in Tensorflow.)

i'm not a lawyer but I would have assumed "probably", unless there's a patent. i mean, if it's not this would suggest it's illegal to attempt to replicate scientific experiments.

also, in many cases even for the code provided by the researchers there is an actual LICENSE file included, and it's often BSD or MIT. (Which sort of makes sense -- these two permissive free software licenses are named after the universities they came from. they reflect the academic CS culture around stuff like this.)

(they're almost taking credit for Pytorch as well). Sure, this kind of work wouldn't be possible…

It's a company blog. It exists to highlight applications of the company's products. I don't see why you are bothered, both of those statements are factually true.

Normally I wouldn't be bothered, but in this case I saw people being misled into thinking Nvidia did this work. Given Nvidia publishes a lot at computer vision conferences, there's a higher than usual potential for confusion.

Funnily enough, I think this technology would be better demoed by people doing more natural motions like walking around and doing basic gestures, or dancing in a style that is more fluid. This type of dancing is made to look intentionally "unnatural" (ie: you rarely see people moving like this in your daily life), which makes it a bit difficult to tell how much of the strangeness/unanny-ness comes from the dancing st…

I would like to see the moon walk of MJ :)

I'm worried about the social ramifications and moving us one step closer to "post-truth". Not much we can to do stop it at some point, but if a certain pee tape came out in the next year, there'd always be a reasonable doubt to its veracity.

Yeah, I don't think people are lending enough weight to how big of a deal that is. We're heading into a world where it would not be very hard to bombard the public with a large number of long form videos of highly convincing videos of anyone in the world ranting on any topic and acting out anything they want, and we would have borderline no idea if it was legitimate. Combining that with our media climate and already…

We've had digital and video manipulation for years, it leaves behind pixelated artifacts though and can be spotted (E.g. see captain disillusion on youtube).

But yes there's going to be a big market for tracking fake data sources in the future. We're already seeing tools to track fake twitter accounts, fake instagram followers, fake amazon purchase reviews, this is an ongoing trend.

That might be intentional. We're used to seeing people walk, so it would be easy to point out flaws in transformed video of people walking. With the unusual movements, we attribute it to the moves because we're not used to seeing them.

I disagree that it is a big deal. There'll be brief period when many people don't know about it, or don't know how mainstream it is, but when it will be done. Then people will realise and there will be a cultural shift where video evidence is significantly less trusted.

So this is a cool demo --and it has applications in cinema, MVs, etc. But, this is being presented as something which could allow Jane Q User to portray herself as an accomplished dancer --just transfer a style onto herself. Maybe I'm in the minority, but I think if we take this idea and walk with it, it has the potential to trivialize actual accomplishment. Maybe I'm overthinking it.

It will just shift it.

They said the same thing with any new artistic medium. Digital cameras, photoshop, Instagram filters, MIDI music instruments, etc.

Practically all singers use "pitch correction", which is essentially "autotune that's not done for artistic effect". If done properly, it's not really janky or fake sounding at all.

I want to plug Jacob Collier though, who doesn't use pitch correction because it's less in tune than where he wants to place the notes naturally, up or down a few cents depending on the note's relationship to the prevailing chord.

He's a maestro, love his iharmu vids especially

I loved watching the movements in the "Detected Pose" corner. I felt like I could see the forms of the dance more clearly. I wonder if ML could learn aesthetically pleasing dance forms, then perhaps we could get some generative choreography!

Interesting. If we could grab audience wide fmri at the next nutcracker for training, right ?

Edit for labeling

There's a difference between using it deliberately and using it because the singer can't sing. I wonder if in 20 years time it will sound incredibly dated, much like 80s synths do today. I'm not particularly against auto tune and ultimately most people don't even notice it being used, but I do sort of understand where the GP is coming from. If your idol can't actually sing, and you saw them live and it's rubbish, wou…

Sure, I agree with you for the most part. Except that if you're going to see one of these autotune singers live with the hope that they're able to sound exactly like the record then you're setting yourself up for disappointment. Would you feel cheated if you found out that the magic show you went to in Vegas was just sleight-of-hand and trickery? :) I personally dislike it too, but I'm not going to say it's not artis…

A lot of people can't tell that someone's auto-tuned. They're not aware enough.

Like most people wouldn't even realise there's a bass line vs a guitar.

As for 80s synths, in my opinion there are a lot of otherwise great songs that are ruined by those travesties. I totally appreciate they were breaking new ground, but remastering some of those tracks with modern synths would make the songs sound a lot better.
