ai;dr MLP trained on 8 questions achieves ~0.3cm height error, ~0.3kg weight error, and ~3-4cm for bust/waist/hips measurements. https://www.mdpi.com/1424-8220/22/5/1885 + some hacking => "we want to productize this"

What does it mean to have 0.3cm height error, when height is one of the 8 questions?

Another comment summarizes this well: https://news.ycombinator.com/reply?id=47901082

But yeah, it's reasonable to obfuscate that fact form the user

(Cofounder here) I talked to really big fast fashion brands on that subject. Oftentimes they dont even have the garment cuts at hand. They sort of outsource big part of the designing process to the supplier (Bangladesh, China contractor). Fashion Technicians are handed samples and they iterate on them, but they can't reproduce the actual fabric dimensions that easily. The fast fashiuon brands are very hard to get them to experiment with such solutions for that matter - it would interfere with very fast and scrappy process thats in place

Thanks, this matches what we're seeing. Trying to establish relationship with some brands, this is the problem we hit. The clothing batches can be very different from each other - cut-by-hand problem. So they don't have sewing patterns to drape and even if they have the final clothes can be different. Plus they don't want to share the patterns/technical details.

So on business side despite the clear benefits, for now we have hard time finding interested brands. Probably part of it is that we're very technical, technology-focused guys. But we're evaluating both paths: whether the mass-made item will fit, and tailoring for a specific person. Will see how it works out.

On the scanner side. The software approach beyond the less friction also have a benefit of predicting the future shape: "pregnant me in 2 months" or "me with 3kg less". Or simpler: my measurements changed since last month and I don't need to rescan. That's harder with hardware.

Like ... who/why would downvote this? This is definitely manipulated.

My guess, the article itself is clearly AI authored and there are a fair number of us who don't particularly like the writing style. Further, it implies something about the original human's own valuation of this work - if they decided to let the machine handle it, why should I spend my own time reading what they didn't bother to write?

I don't like AI slop either, but we're both non-natives, so we did a run of AI after initial draft for the reader's comfort. We'll try to improve on the style

Twenty or so years ago, Levis had a program called Personal Pair (they paired with a firm/product called Intellifit) where you would step into a millimeter wave 3D scanner and get your precise measurements. https://www.youtube.com/watch?v=G1IceHjADbQ Which you could use to get a custom pair of jeans made just for you. This failed partly because the target market turned out to be middle-aged adults (that buy fewer pai…

Privacy is close to my heart too. It's just a balance between privacy as a need vs operation speed and intellectual property. To be decided.

Inference can be totally done client-side. Later measurement tuning would be much harder.

So perhaps you need to present them with a more complete solution. Develop or source a faster laser cutter. And find a small factory in an area with skilled labor (central North Carolina still has people who can cut & sew). And develop a process in the factory to keep all the panels for one item of clothing together from cutting to sewing to shipping (maybe a bucket?).

It'll be a bespoke item at premium prices, no question. How big is the market for this? I don't know, but my feeling is that it's older women.

How big are the pockets and is it sex determined?

Yes, sex is one of the inputs. But regional fat distribution isn't something we model or evaluate yet. But going to work on it.

For the humour impaired, pocketsize in women's clothing is contentious because for reasons determined by the fashion police pockets are unsightly and either fictional, or tiny.

One time, I found women's jeans with tiny pockets but the bottom seam could be pulled undone to reveal a man size pocket of cloth below. That was classy.
