You mention black and white colorization and that was my first thought upon seeing this. The statues are already super “photo-realistic” so I’m guessing this was a pretty similar process.
On a completely different note, I am not sure what you’re getting at with the racial stuff. Like what are you suggesting? That perhaps some of the emperors weren’t totally Caucasian but rendering them as such from the best available evidence is somehow racist? In my humble opinion, trying to find racial undertones in every tangential thing is a distraction from the real conversations that we should be having. And there’s a real possibility of alienating people that are otherwise sympathetic to the cause.
- mLuby 6y ago> trying to find racial undertones in every tangential thing In this case it isn't tangential but central, since the point is extrapolating physical appearance from incomplete data. It matters if the results predict inaccurate racial features because plenty of people unfortunately care about kind of thing. And remember that laypeople read "researchers used machine learning" as "super smart people used advanced science to get this result so it's probably true."
- trav4225 6y agoBut, isn't "extrapolating physical appearance from incomplete data" the entire point of this project?
- GolDDranks 6y agoIt is, but the criticism is that it's easy to misunderstand and/or skip over the "incomplete" part, and get a wrong conclusion that the results are more accurate than they actually are.
- frereubu 6y agoMy understanding of the original point is that ML models are trained on a data set. If you train the model on a data set that is only made up of white faces, the results will be whiter than if you train it on a data set that is made up solely of black faces. They said they'd like to know the makeup of the data set that the model is trained on to more fully understand how the results were produced.
- darkerside 6y agoBut there was no attempt made to account for the incompleteness of the data in this particular known way.
- Fuzzwah 6y agoI feel like the current climate of society shows that people who have such a simplistic view of science don't tend towards "smart people said this, so it must be true"....
- acqq 6y agoThey do, they just often can’t make a difference between snake oil salesman from a good scientist. And that’s exactly the point.
- LifeLiverTransp 6y agoOh, you can easy distinguish the scientists from the snake oil salesman. One faction starts a fistfight mid-presentation over a "debated" detail - while the other goes smoothly into the sales pitch.
- sengstrom 6y agoThese images were rendered with a "white" bias. Facial features is one thing, but skin color is clearly not conveyed by statues, yet a clear choice was made here.
- giantDinosaur 6y agoYou can't just claim this without suggesting what's actually wrong. What is wrong, and where are the good sources from which we can make a comparison? If you're just guessing then you're no better than this ML model.
- ummonk 6y agoGiven the preponderance of blonde emperors, it would be reasonable to assume emperors in general were rather light-skinned.
- bsanr 6y agoWhat is blond, in a two-thousand-year-old context? https://www.youtube.com/watch?v=gMqZR3pqMjg https://www.youtube.com/watch?v=gMqZR3pqMjg
- ummonk 6y agoIt doesn't matter. Non-white people without steppe ancestry are pretty much uniformly dark-haired and don't have names akin to "subflavum" for traditional hair colors, because light yellow/gold hair just isn't a thing, regardless of what exactly they conceive of as "yellow/gold".
- CMCDragonkai 6y agoAboriginal Australians have blonde hair arising independently.
- makapuf 6y agoPretty sure Augustus wasnt aboriginal Australian, though (I see your point)
- trav4225 6y ago> That perhaps some of the emperors weren’t totally Caucasian but rendering them as such from the best available evidence is somehow racist? These days, sadly, yes. The definition of racism has been so diluted in recent years that, as you implied, I fear it's often a distraction from actual racial injustice. Anyone ever hear of the boy who cried wolf? Downvote away! :)
- codyb 6y agoI don’t think gp was implying rendering as such to be racist, but was more concerned about people taking these renders as fact and using them to justify a prejudiced world view. If someone is prone to accepting the idea that caucasians are superior to others they may use something as seemingly innocuous as this neat project to justify their positions and the lack of disclaimers towards the inaccuracies of certain aspects of these renderings may do a small harm societally. On its own it’d be fine but in conjunction with other symbols and narratives it can become part of a larger, more sinister narrative.
- mkr-hn 6y agoPeople on a confirmation shopping spree have plenty of things to buy already. Historical accuracy is still a good aim.
- ericjang 6y ago> On a completely different note, I am not sure what you’re getting at with the racial stuff What I am saying is that this sort of work can lead to people believing these images as true, i.e. "this is what Roman Emperors looked like". If you ask an ML system to solve a problem for which the inputs cannot possibly determine the answer (i.e. the color of a fossilized animal or the skin color from a person's statue), it will give you a highly biased answer. I fear that some laypeople think of ML as "magic software that can do anything" without considering whether a problem is non-ambiguous given its inputs (e.g. something like object classification is less ambiguous than this problem). I'm not saying "burn it to the ground" - I wanted to learn more about what data and model was used to generate these images so that I might understand better where potential sources of racial / ethnographic bias might come from. > trying to find racial undertones in every tangential thing If you read my comments history you'll see that I'm no critical race theorist, nor do I discuss everything in a racial context. Out of curiosity, what "cause" are you talking about?
- fit2rule 6y ago>"this is what Roman Emperors looked like" The same can be said of the original advanced technology used to render a facsimile of the Roman Emperors, and in fact .. many stone sculptors have lost their prestige for the sake of this very same argument. Since culture is a lie which persists only in the telling, this IS what the Roman Emperors look like, now. You shouldn't resist that, because there is no truth on this issue, anyway.
- darkerside 6y agoIs there anything in the HN guidelines about willfully dismissing or obscuring the truth? This comment makes me feel like there should be. Saying "we'll never know anyway so stop asking" is abhorrent to me, and I imagine many on this forum. Not to mention it aims to end a discussion it doesn't understand.
- fit2rule 6y agoWell, the sculpture is a fiction, and this AI generated image is a fiction - what's wrong with acknowledging that these fictions are all we have? Life is a collection of these facsimiles.
- sct202 6y agoColors are can be subjective and somewhat politicized even when there's a written description. It's kind of like how every culture tends to color Jesus to be more similar to the local people, even though everyone knows he's from the middle east. I might call someone blond with blue eyes, but someone else might describe the same person hair with light brown with green eyes. If we had third person choose which colors represented the descriptions, they might pick completely different colors based on what they thought blond or light brown meant.
- brobinson 6y agoWe know what colors some statues originally had: https://art-sheep.com/the-true-colours-of-greek-and-roman-statues-by-archaeologist-vinzenz-brinkmann/ https://art-sheep.com/the-true-colours-of-greek-and-roman-st... Caligula looks to be on point based on the restoration of his original colors in that article. To your second point, that reminded me that Japan's traffic signals use a different color "green" (looks more blueish) than the rest of the world and they have a common, named color that doesn't really map to blue or green in the rest of the world: https://en.wikipedia.org/wiki/Ao_(color) https://en.wikipedia.org/wiki/Ao_(color)
- saeranv 6y agoThe "racial stuff" seems relevant here. Sure, some people try and insert race into everything, but in this case it's a relevant, and interesting aspect of the problem domain. My understanding is that the racial identity of the ancient Romans are actually a lot more ambiguous then most people realize, and the way the author attempts to reconcile that ambiguity has a huge impact on the image output here. And it's an interesting problem, Yann LeCun has discussed a bit about how to account for racial diversity via ML techniques (it's not just about the training data set!). From what I recall, the reason for this racial ambiguity is because ancient Rome (and the entire Mediterranean region) was a cosmopolitan hotbed where many different ethnicities were mixing together all the time. On top of that, they didn't have the same kind of racial constructs we had, and so it's actually unclear what the races of various ancient Romans actually were.
- darkerside 6y agoWould be interesting to sequence their dna, and adjust these based on ethnic generic makeup
- AlotOfReading 6y agoThe way I like to explain it to people is that culture, ancestry, and language are 3 separate (but related) things. Knowing one doesn't necessarily tell you anything about the other two. In this case, it would tell you that the genetics are not sufficient to describe the categories of Roman ethnicity without additional justification that in this one particular case, they are.
- darkerside 6y agoI meant adjusting the images based on busts, not categories.
