I had some fun with StyleGAN a couple years ago. I should probably have written this up, or something. Some others I showed it too thought I should. But I never took it too serious. I was just bored over a couple weekends when I had access to some beefy GPUs. And y'know, it's quasi-porno.
I opted for dudes not gals. Part personal preference, partly because I happened to get my hands on an enormous dataset of hot shirtless guys taking selfies.
The initial results were rather poor: https://i.imgur.com/npzDcCL.jpg https://i.imgur.com/npzDcCL.jpg
That's around when I realized how important the training data really is. Too much variation in pose. So I trained a model that detected the face, nipples, and belly button, and aligned them vertically with that. Then I briefly skimmed over the dataset manually, and deleted anything that just varied too much from the median, in a rather arbitrary way.
Results were better: https://i.imgur.com/bS7ERC6.jpg https://i.imgur.com/bS7ERC6.jpg
So I just let it churn away for a week, heating up the basement. Some final results with narrow truncation and style transfer: https://i.imgur.com/rhnWnpK.jpg https://i.imgur.com/rhnWnpK.jpg
One thing I find intriguing is how bland those men are, really. Oh, beautiful, but too classically beautiful. In a sense, StyleGAN is a compression algorithm, and highly truncated outputs are something like a median of the inputs. So the above reflect a sort of "average" idealized image, that contains the traits most commonly found, in the media I trained it with.

- whiddershins 4y agoScott Adams claims that 30% of people have no sense of humor whatsoever.
- CodeMage 4y agoScott Adams has claimed a great variety of things over time. A lot of those claims don't hold up well under scrutiny, so I'm a bit skeptical of this one. Especially since I'm one of those people who think Dilbert stopped being funny a long time ago.
- brewdad 4y agoBut Scott Adams as himself is hilarious. It's like an AI-bot gone awry except that there's actually a real person tweeting out to the world.

- Judgmentality 4y agoHow is this a personal attack? Besides that, you already removed the parent comment so nobody can even find this now without clicking my profile. > I think this just might not be your cup of tea. That's fine. We all have our preferences. I don't see how I could be any nicer. > Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith. I feel like you're ignoring your own guidelines. Please lead by example.
- cirgue 4y agoBecause when presented with a bunch of pictures of hot shirtless dudes, thinking “how can I apply cutting edge technology here?” simultaneously isn’t most peoples first instinct (regardless of your gender identity or sexual orientation), but is immediately relatable if you’re a technology nerd. It’s both unexpected and familiar, and that’s the magic formula for humor.
- Buttons840 4y agoThose first images remind me of the "brainlet" memes you often see in high-quality shitposts (something I appreciate more than the average HN reader I think).
- jancsika 4y agoIn your example link here: https://i.imgur.com/bS7ERC6.jpg https://i.imgur.com/bS7ERC6.jpg you show one fellow with a smartphone stabbed through the chest, plus a headphone cord fused into his forearm veins. When you "let it churn away for a week," which of the following is more likely: 1. Smartphone Stab Wound Guys decrease in likelihood 2. More realistic-looking smartphone stabs In either case it doesn't exactly inspire confidence in self-driving cars.

- jiggawatts 4y agoIn a future Tesla shareholders meeting: “Version 10.2 can detect children crossing the road with 97% accuracy, and collides with them dead on at the same rate. Those well publicised close calls are now a thing of the past!”
- spiderfarmer 4y agoTo be fair if a kid crosses a road dangerously in front of human drivers there are a lot factors at play that impede with the accuracy of those drivers. No system is perfect and we shouldn’t expect that.
- low_tech_love 4y agoAbsolutely, but we cannot assume that machines have the same “right to make a mistake” than humans. If a machine kills a person, somebody is responsible and will get sued.
- cyanydeez 4y agoThe good news: we kill less people. The bad news: when we do, it's unfathomable how anything but a computer could do this
- forgingahead 4y agoThe community can't have too few blog posts / ML experiment writeups, so do write a blog post on your experiences, it would definitely be interesting.
- dzhiurgis 4y agoWabi-sabi is a thing. Friend noted years ago how kids who are super aware of their weird teeth or hair colour turns out to be their most beautiful trait later.
- chimeracoder 4y ago> partly because I happened to get my hands on an enormous dataset of hot shirtless guys taking selfies. I feel like this is burying the lede. I'm very curious where you sourced this training data.
