Visiting the website I feel as if there's something to be learned about the current state of anime. Or maybe it's just their training data and I'm reading too much into it, dunno. The model has no idea about what arms are supposed to look like [1] but has no problem making sure that the resulting abominations are wearing underwear only. Also missing: men.

I think it's a bit of both. There is a pretty large fanservice/borderline NSFW/smut and similar Anime industry. But there are also quite many Animes which don't have the problem or at most have a very small amount of fan service "sprinkl in". But in this generator the borderline NSFW stuff seems to be the main topic.

  I let it run for a minute or so and every image appeared to be fully clothed or at least “bikini clothed”. Psychedelically distorted? Yes. NSFW? I guess it would depend on your W.

    I did run through it for a while. A while it indeed get's better after some time (interestingly, why does that happen?) it doesn't change that most characters are in implicit poses. Maybe clothed yes, but you can also put clothed characters in poses which imply sexual content. I also realized that the source of the images show is largely from Danbooru (with safe mode), which pretty much explains everything ;=)

      Ok sometimes most characters are in implicit poses + likely in underwear/swimsuit and sometimes just some characters are in implicit poses + likely in underwear/swimsuit. It seems to be in flux.

Sometimes it gets arms right. On the rare occasions feet appear, they're totally wrong. Boobs, the system models very well. This probably reflects the training data.

  Boobs? Check. Butts? Check. Why not put them together: https://thisanimedoesnotexist.ai/results/psi-1.0/seed3375.png https://thisanimedoesnotexist.ai/results/psi-1.0/seed3375.pn...

That's because each and every one of them is a stylistic genre called moe, that emphasizes the cuteness and sexual appeal of the characters. The a.i. was clearly trained using moe only. Moe and fan-service tend to walk as one. You will also notice that the overwhelming majority of the characters look female. A high to absolute number of female characters is also common to moe. I'd actually be interested what turns out if an a.i. actually be trained from a completely random selection of last year's releases in animation from Japan and whether it would manage to keep different art styles apart, or somehow blend them. I don't really believe in the common claim that it is easy to recognize animation from Japan from stylistic elements, it just so happens that it seems that moe is often what is being talked about: - https://i.ytimg.com/vi/dR-648aYD6s/maxresdefault.jpg https://i.ytimg.com/vi/dR-648aYD6s/maxresdefault.jpg - https://pbs.twimg.com/media/ENxzRVVVAAIzbOC.jpg https://pbs.twimg.com/media/ENxzRVVVAAIzbOC.jpg - https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQHB0hiKgtyNbA1R9F2sTtRUJt63aoPydGIfA&usqp=CAU https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQHB0hi... - https://i.pinimg.com/474x/57/71/bb/5771bbd550c96e1799659e2a0445f58d.jpg https://i.pinimg.com/474x/57/71/bb/5771bbd550c96e1799659e2a0... - https://assets.mycast.io/characters/monkey-d-luffy-12086-normal.jpg?1567286064 https://assets.mycast.io/characters/monkey-d-luffy-12086-nor... - https://www.indiewire.com/wp-content/uploads/2016/07/blame.png?w=780 https://www.indiewire.com/wp-content/uploads/2016/07/blame.p... - https://miro.medium.com/max/3840/1*opC8ndIEWzVartwBG16Chg.png https://miro.medium.com/max/3840/1*opC8ndIEWzVartwBG16Chg.pn... I think it would be quite interesting to see what were to happen if the a.i. would be trained across a library of very different art styles.

  > I'd actually be interested what turns out if an a.i. actually be trained from a completely random selection Something I noticed is that AIs appear to have trouble with differentiating perspective vs art style. What I mean by that often characters are in 3/4 view, which naturally means one eye will be smaller than the other due to perspective. But some art styles have bigger eyes than others. What I see sometimes is that the AI then produces an image where each eye comes from a different art style. It doesn't appear to account for the concept of a three-dimensionally spherical head and how perspective works with respect with such shapes. It most certainly would not produce good results unless you specify that stuff like shirokuma cafe[0] characters are not human.

That's sampling bias - danbooru2019 is mostly old touhou fanart plus whatever a subset of horny men who like tagging things have uploaded from pixiv. Worldwide anime and related media have a mostly female audience and certainly don't lack male characters. In Japan women write more fanfiction relative to men who draw more fanart, I think, but I've never counted.

  Women who made R-18 fan arts tend to avoid their arts tagged to original name, this is also a big factor. They also do search prevention (検索除け) by like inserting random character between name.
  - astrange 6y ago
    That's true but since danbooru relies on manual uploads by fans who liked the pictures anyway, it isn't much of an issue. There are other sites with more female users (eshuushuu and zerochan iirc) but danbooru's data is better because of a combination of 1. not allowing horrible poorly drawn fetish art or selfposts 2. ignoring the fact that most of the good artists don't want to be posted in the first place.
