One step closer to the movie Her

Seinfeld. George gets married because of a typo into an AI handwritten letter service he sent to his girlfriend.

Is this spitballing, or did that actually happen in the show? My memory is v.fuzzy.

I've had a project idea similar to this in the backlog for years: personalized signature generator that can be used to deal with dinosaurs that still want printed, scanned and signed documents. Basically I want to take a pdf, turn it into fake scan image (add noise, some inkjet smear lines, random skew etc procedurally), then generate signature image to paste over that. Zero dead trees and screaming at printers invol…

You might as well make a scan of your actual signature and make the generator overlay the image instead.

It is trivially recognizable in PDF viewers like Adobe Reader that a signature image was pasted in (the image rectangle around the signature highlights), and can therefore be rejected as not being a genuine signature, unless you turn the whole page into an image to make it look like a scan.

Any idea what causes this?

Neural nets often fail with (repetitive) gibberish output when the input is too different from the training data. This model appears to take in the entire text input at once or look ahead at the next input letters, so the unusual "bla bla" at the end can mess up outputs near the beginning.

The "bla bla" actually doesn't do much, that's the "My first" that triggers it most of the time. I only added the "bla bla" in the end to make the line longer because it looks better that way, but just writing "My first" or even "My f" is enough.

It is described as "Realistic handwriting generator. Convert text to handwriting using an in-browser recurrent neural network", so, unlike GPT, it is not a transformer and it is small, so it most likely doesn't take the entire text input as once. Most likely, it simply overshoots the previous stroke and decides that a loop is the most appropriate way to continue, then it overshoots that loop, and again, and again, until by chance it stops overshooting and proceeds to the rest of the text. Cursive style like #2, the need for precise strokes (high legibility) and specific letter transitions seem to exacerbate the problem.

My first name contains one of the fewest used letters of the alphabet and in first position nonetheless: Xavier Let me tell you: the training data did not contain that many X to begin with :D The Xs at best look like Ts, at worst like malformed Os. Always funny to find the blind spots of some piece of tech.

i recommend trying the phrase "sphinx of black quartz, judge my vow!" on style 6, with legibility set to maximum. sometimes it looks roughly right, sometimes it opens with "sphnnneoooeoeoeoeoevorneroerof black quartz"

I like that phrase. On style 2 with high legibility (~75% to the right), max speed, and min width I ran it a couple times with good success then it looped off the screen for the next few runs.

The same settings but with min speed got caught at the z, creating what looked like repeating waves then a few letters that I couldn't place from the phrase.

Also amusing are the loops that get the tops cropped even though other letters extend higher.

I think all of the car dealers I've dealt with the past decade are doing something like this. I get "handwritten" notes from them a few times a year telling me the market is hot for my 5 year old Subaru and I'd be a fool not to trade it in. I don't know if it's a machine writing the notes or if that's what salespeople do when they aren't busy.

Most likely mass printed for targeted mailing with a handwriting style font. I remember getting something similar in the mail written in what appeared to be blue ink from a ballpoint pen. Only to find out my wife got an identical piece of ad mail , just with her name at the top.

Last year there was a discussion about someone making a setup to send handwritten plotted letters here: https://news.ycombinator.com/item?id=28587458

I noticed some similar letters several years ago and had a pretty negative response once I figured it out. But these might be enough better I wouldn't notice unless of course I see another one like you did.
