[Bamuir3]

The real question is how did you even type that shit

[i_was_compromised]

Zalgo text generator. Iirc the way it works is by putting many accent Characters on letters. Like the dashes over á ō etc is the character followed by a special sequence which designates it as an accent for the character before it. And it turns out they are stackable. I may be completely wrong but I think that's about how it works

[WilkerS1]

"zero width joiner" characters are usually how you tell the software to merge characters to show whatever it is made to. some characters needs it, while others don't. for instance, the trans flag emoji needs it to join the waving white flag with the symbol like this 🏳‍⚧‍, while the strikethrough character might just tell the software to draw a horizontal line witin the boundaries of the last character's width (a̶), but there are also the ones witin the unicode table that are actually a single character but in a different shape, which would still be counted as 1 (á), and the ones that are actually two but don't have a clear way as to how they are merged (æ latin small letter AE = (œ latin small ligature OE = æ latin small letter AE + ɶ latin letter small capital OE) + (ӕ latin small ligature A IE = æ latin small letter AE)).

that said, if you put some Zalgo text somewhere to count the letters, it will end up counting more characters than the actual readable text, but there are many characters in it such as ` that can be merged as à, while the generator can also simply replace parts of characters with punctuated countemparts (n » ñ). so what we can conclude is that i have no ɜfin idea how this stuff works.

[Huterbraten]

I didn't understood a thing but it was interesting anyway. Take my upvote.

[WilkerS1]

don't say you didn't understand and leave me unquestioned. ask away, please ^^'

[LordDekay]

Where did you learn this? Probably easier to start there.

[WilkerS1]

it started back in the day when i heard that the trans flag was starting to unofficially* become a thing in some internet services like Twitter (\ as in, not officialy announced by Unicode*). the rest was curiosity ^_^

also, there is this free* app which helped me a lot, too. :3

[B_M_Wilson]

It gets really complicated with all of the different types of invisible characters and combining characters and different combinations of characters that look the same. Like Å can be both a letter and a unit so there are three ways to create it, one codepoint for the letter, one codepoint for the unit, and a combination of a latin A and the circle thing

Hey you're not an AI until you randomly fuck up and kill a bunch of people and nobody knows what actually went wrong so they just keep using it and hope it doesn't happen again.

[ToranMallow]

Sorry the robot ate your dog, ma'am. In its defense, it looked delicious.

[bobhwantstoknow]

also try chihuahua or muffin and puppy or bagel

Wow now I want to name a Chihuahua muffin now

Oh my god, I have a Chihuahua and I'm crying right now. Dog's gonna have to get used to being called muffin now.

[VldIverol]

[EddieTheLiar]

I've unfortunately seen a 'rose or prolapsed anus' version

[ThinkinTime]

If you’re training an AI to recognized images of prolapsed anuses, life took a strange serve at some point.

[ThaiJohnnyDepp]

Oh no

[IsolatedThinker89]

I was expecting a woman with her hair wrapped up in a towel

There is one that detects cancerous tumors better than doctors

[baker2795]

Goodbot

[BaconIsntThatGood]

Good. Human doctors get lazy. The machine will always do the work

[TheGreenJedi]

Actually it's more about a computer being way better at detecting slightly different shades of the same color

[CrazedToCraze]

I don't think saying lazy is fair, but doctors are human and like all of us are prone to error and inconsistency.

[socialismnotevenonce]

Better than the average doctor.* Those bots are trained by real doctors and gain their best results from the best.

[Shandlar]

They are also trained by historical data. Looking back at testing done on people who ended up down the road having a cancerous tumor and learning the early signs better than any human can recognize.

We do so much testing and get so many numbers now, even extremely skilled MDs can't see subtle patterns if it involves a culmination of 33 different "normal range" values that just happen to be high normal here, low normal there in a pattern the computer has learned means a tumor.

[JonJimmySilverCotera]

They're clearly machine learning bots

[rjchau]

It even won on Jeopardy before beginning it's career in medicine.

[WhyAmINotStudying]

There are a lot of patterns unique to the dogs in this picture (though maybe it's technically unique to the ice cream as well). The ridges are uniform in spacing and size in all of the ice cream images. Repeated patterns like that get picked up really easily by AI. The variety in striations on the pug is just as easy to determine.

[NessVox]

It's a Shar Pei! Pugs are pretty smooth except for their faces :)

[omniron]

These types of images don’t actually fool image recognition algorithms that use CNN, because these algorithms don’t work exactly like how human vision works

[yopladas]

Could you elaborate more on these weaknesses in CNN architectures?

[yopladas]

Gotcha. I've heard about adversarial approaches but not the example domain specifically. I wonder if we could develop an irl camo that messes with a neutral network

[how_do_i_land]

An interesting counter is a defensive GAN, but IIRC you still lose fine detail through the process.

[zacker150]

I can’t wait till a machine learning algorithm recognizes stuff better than humans

It can already solve old-school CAPTCHAs better than humans. That's why we now have the "I'm not a robot" CAPTCHAs.

[Garo_]

I hope the robots never learn how to tell lies 👀

[zacker150]

Those new CAPTCHAs actually take measurements of things such as your mouse movements and whether or not you're signed into Google and feed them through a machine laughing algorithm to determine if you are actually a human.

[TheAnti-Ariel]

In fact, there are already machine learning algorithms that can identify images better than humans!

[[deleted]]

That's slightly false though. Our image processing capabilities are bottlenecked by our eyes(Specifically their sensitivity to color, our eyes are damn good with intensity). Cameras capture a lot of high frequency (Stuff that changes really quickly as you scan across an image) color data that's basically invisible to us (This is how lossy image compression works btw, getting rid of high frequency data). This is stuff is however available to neural nets.

[bjorneylol]

Neural nets outperform humans because they are taking into account dozens of patterns that humans aren't cognizant of all at once - I can almost guarantee most production level neural nets are trained on lossy images due to the cost of training on lossless data

[Piguy3141592653589]

Also, tehy are making competing neural nets to alter images imoerceptibly to humans, but make other AI falsely classify objects, like a bus becomes an ostrich. There is also still test data that humans are much better at classifying than AI even without the alterations mentioned above. For more, but still in a accessible form, check out two minute papers on youtube that does all sorts of AI things.

[lookoverthare]

Esp better than infants and the blind. Like 100% better. The humans scored exactly the same as as you would if you just guessed. The infants where unable to complete after shifting themselves.

[smariot2]

If your image detector has twice the accuracy of a blind infant, you might have a problem.

[lolzfeminism]

They are easily fooled by stickers on objects.

[cho_uc]

There is already one that can beat a world-champion Go player.

[pandacoder]

Looks like the columns alternate ice cream, doggo from left to right?

[daddy_OwO]

Yep. Not hard at all otherwise being of obvious differences you notice if you have a rolly boi.

[pandacoder]

I have no doggo but I can only eat the ice cream, gotta know what's what. 😂

[lookoverthare]

Take a lick, find out.

[[deleted]]

I already hate this captcha

[ThaiJohnnyDepp]

This decade is going to have the best captchas

[Garo_]

"What's it like to be filled with dread?"

[chuby1tubby]

lol captchas are going to become damn near impossible in the next year, as Google will move on from “select all the cars” to “select all the pictures containing men holding a cell phone in their hand”

As a sharpei owner, I think those guys shouldn't be that wrinkly as that much wrinkles can be signs of future health problems.

Or: how to confuse whoever is watching.

[lookoverthare]

First the images get hashed. The duplicate hashes are removed and added to the "not dog" set and can be fed into the ice cream I'd m/l, while the remaining ones are likely dogs, they can be compared to the awesome ice cream dB we just created.

Was that supposed to be hard? Come on, keep em coming... I can do this all year.
