Researchers say objects can hide from computer vision by seeking out unusual company that trips correlation bias Computer vision systems display “correlation bias” that makes it possible to create adversarial images, that could have real-world consequences such as messing with self-driving cars’ ability to accurately interpret road signs. That assertion was made today at the Black Hat Asia conference by Paul Ziegler, CEO of risk …
I'm not a massive fan of gay sex but I don't think it follows that everyone else should abstain from it. See also tea, toast, scones, loo roll orientation, whether you wear you mask in your car*, how you like your steak, etc.
I don't care if you put milk in your Earl Grey, I won't judge, just don't put it in mine. Or systemd in your distro ...
* someone literally told me that this was their "biggest bugbear at the moment" and seemed rather hurt about my response that I could think of at least three reasons of the top of my head why someone might be wearing a mask in their car and exactly none as to why they thought they had enough spare cognitive bandwidth for that whilst navigating 1.5 tonnes of metal through a space shared with other road users.

I'm not scared. Pinapple on a pizza with ham on is lovely. Hey! I'm a child of 1970s England. Pineapple on grilled ham was the height of sophistication! That's a garnish, that is...
My Mum's idea of cooking a curry around 1980 was some curry powder (no chilli, cumin, garam masala, ginger, garlic etc) added to a chicken stew - and then further to add raisins or dried apricot. Thus imbuing it with the savour of the mysterious East...
However I do still think that ham and pineapple go quite well together. My favourite pizza is a proper Fiorentina (spinach and egg) or just something simple with lots of mozarella and tomato. But if I'm having Dominoes, which is already covered in a weirdly sweet tomato sauce, why not bung some pineapple and ham on as well?
Dominos alfredo sauce (not the garlic parm version), bacon, pineapple, ham, mozzarella cheese, on crunchy thin crust.
If you're feeling more adventurous, swap the mozzarella out for provolone and feta.
Wash it down with a decent beer to combat the salt.
I've been on a sour ale kick lately.
Vegan will only stop you getting the cheese, which makes things pretty tricky - vegan cheese substitute is foul, I'd leave it off entirely. But gluten free is worse. I have a frend with Celiac's who helped me install my pizza oven a couple of year ago, so I've been tried to find a substitute for 00 flour to pay him back. So far the best option seems to be xanthan gum, some sort of non-wheat flour, and you have to cook it like a pancake first rather than rolling it out. Gluten is one of those things you don't miss until it's gone.
@ChrisG why in gods name would you include pesticide free in that list? Are you saying pesticides improve the taste? As for unsweetened, I'm not 8 anymore. Loading something with sugar (or HFCS for the yanks) or Aspartame is not appealing. I now try and buy pickles at the Polish store if I can, as they're not loaded with sweeteners like the supermarket stuff.
Hubert Cumberdale,
What? Scones without jam? Nooooooo! Thin layer of raspberry on the scone, and then very large dollop of clotted cream on top. One shouldn't spread the cream, so much as squash it flat-ish with the spoon so that you can fit it in your mouth easily.
This is why the cream can't go on first, because then the jam will slide off the top.
I'm bringing greed to the jam/cream debate, and therefore there's only one way to go. Jam, followed by CREAM!!
There was a debate on this very topic between my wife and my cousin... there was much banter until, finally, the wife ended with a classic..."if you are not worried about blocking your nostrils with cream, when taking the first bite, you haven't got enough cream"
The cream IS the best bit.
Strangely enough the origin of clotted cream is sometimes thought to be as a preparation for use instead of butter. Butter being cold churned is prone to ending up rancid, particularly in the days before fridges. Clotted cream on the other hand has been heat treated and actually survives pretty well. This idea of the origins is the normal argument for 'cream first'.
Boudreaux & Thibodeaux were driving around town one night, and coming up to a red light, Boudreaux runs right through it, not even slowing down.
Thibodeaux says, "Boudreaux, you ran dat red light. Be careful !"
Boudreaux tells him, "Don't worry, Hebert does it all de time, and nuttin ever happens."
A few minutes later, another red light, and Boudreaux runs it too.
Thibodeaux screams at him, "Boudreaux, you keep running dem red lights, you gonna got us killed !"
Boudreaux assures him, "Mais I done tol' you, Hebert does it all de time wid no problem. Don't worry."
The next intersection they come to, they have a green light, and Boudreaux slams on the brakes, coming to a complete stop on green. Thibodeaux asks him, "Why you stop for de green light ?"
Boudreaux, looking cautiously both ways tells him, "Mais, if I gots de green light, I gots to be careful, 'cause Hebert might be passing de other way ! "
Because putting your poster over a legal road sign would be illegal. The article is talking about AI vision systems getting confused by context where the context might be changed inadvertently by legal means.
As the article states, they were being inquisitive, not adversarial, and so not looking for actual attack vectors,
eg what if a grocery delivery lorry, which are often covered in pictures of food, is stopped by the roadside near a road sign? Or big advertising hoarding with a dog and a ball? Maybe the AI can't see the road sign now, or assesses that the huge dog might run into the road.
Yet another demonstration of the inability of AIU to actually think. If the hash of the pixel array approximates to X more closely than to Y, AI assumes it is X, and conversely if the hash deviates far enough from X, AI assumes it isn't X. The intelligence demonstrated by this is extremely artificial.
"The intelligence demonstrated by this is extremely artificial."
It's not intelligent is the biggest problem, it is just a tarted up version of a logic gate, I suspect the average hamster has better decision making intelligence and far less likely to run you and your autonomous vehicle into the path of a speeding juggernaut.
The current systems dont cope too well with any number of situations including posters on nearby hoardings or walls. We all know that software is difficult, now with an image it becomes even harder, is that huge face visible to the camera someone really close or a large advert? Humans use a hell of a lot of context when viewing, far more than I think we give credit for.
We tend to judge these systems too harshly, forgetting that its easy to fool human perception. This is especially true when driving because events are happening too fast for you to minutely examine a scene -- you have to get an overview in a fraction of a second.
If there's a fault with machine vision is that it behaves like a student (learner) driver -- it focuses on everything, tries to see everything and as result only sees exactly whats in front of it and in the context of what it expects to see. I daresay it will improve with experience -- while its learning it might be advisable to avoid routes and situations that present too complex problems for it to easily handle.
