epitome acknowledgment technology may be sophisticated , but it is also easily duped . Researchers have fool algorithms into confusingtwo skiers for a heel , a baseball for espresso , anda turtleneck for a rifle . But a Modern method of deceiving the machine is dim-witted and far - reach , regard just a humble sticker .
Google researchers produce a psychedelic gummed label that , when range in an unrelated double , tricks deep find out system into classifying the image as a toaster . concord to a late state research paperabout the attack , this adversarial eyepatch is “ scene - main , ” meaning someone could deploy it “ without anterior cognition of the lighting conditions , camera slant , type of classifier being attacked , or even the other items within the fit . ” It ’s also well approachable , given it can be shared and print from the cyberspace .
A YouTube video uploaded by Tom Brown — a squad member on Google Brain , the company ’s recondite learning research team — record how the adversarial mend works using a banana . An image of a banana on a table is aright relegate by the VGG16 neural meshwork as a banana , but when the psychedelic toaster gummed label is placed next to it , the internet classifies the image as a toaster .
That ’s because , as the researcher mark in the newspaper , a deep encyclopaedism poser will only detect one token in an image , the one that it considers to be the most “ salient . ” “ The adversarial patch effort this feature by producing stimulant much more salient than object in the material world , ” the researchers wrote in the paper . “ Thus , when attack aim detection or image segmentation exemplar , we expect a targeted toaster patch to be sort as a toaster , and not to affect other circumstances of the epitome . ”
While there are a number of ways research worker have suckered political machine learn algorithmic program into seeing something that is not in fact there , this method is particularly consequential give how loose it is to carry out , and how inconspicuous it is . “ Even if humans are able to notice these patches , they may not understand the intent of the maculation and instead look at it as a form of artwork , ” the researcher wrote .
Currently , tricking a political machine into thinking a banana tree is a wassailer is n’t exactly a menace to beau monde . But as our world start to more and more incline on image identification technology to operate , these types of easily executable method can make for mayhem . Most notably , with the axial motion - out of self - driving cars . These machinesrely on paradigm recognition softwareto see and interact with their surroundings . Things could get dangerous if thousands of pounds of metallic element rolling down the highway can only see toasters .
