Machine-learning-based image classifiers are vulnerable to "adversarial preturbations" where small, seemingly innocuous modifications to images (including very trivial ones) can totally confound them.
This 3D-printed sculpture of a turtle has been subjected to a tiny adversarial preturbation that reliably tricks InceptionV3 image classifier into thinking that it's a rifle. The preturbation is visually imperceptible, and a version that the human eye perceives as identical is correctly classified by InceptionV3 as a turtle.
The same research team has preturbed an image of an adorable kitty-cat so that InceptionV3 always mistakes it for guacamole.
Here is a 3D-printed turtle that is classified at every viewpoint as a “rifle” by Google’s InceptionV3 image classifier, whereas the unperturbed turtle is consistently classified as “turtle”.
We do this using a new algorithm for reliably producing adversarial examples that cause targeted misclassification under transformations like blur, rotation, zoom, or translation, and we use it to generate both 2D printouts and 3D models that fool a standard neural network at any angle.
Our process works for arbitrary 3D models - not just turtles! We also made a baseball that classifies as an espresso at every angle! The examples still fool the neural network when we put them in front of semantically relevant backgrounds; for example, you’d never see a rifle underwater, or an espresso in a baseball mitt.
Fooling Neural Networks in the Physical World with 3D Adversarial Objects
Google's Sidewalk Labs convinced Toronto to let it build an all-surveilling "smart city" on a small patch of lakefront and then promptly shenaniganized things, breaking all its privacy and transparency promises and prompting a mass exodus of its advisory board members and other watchdogs.
This past September, a savage fire cost the world dearly: the National Museum of Brazil in Rio de Janeiro, along with 20 million unique artifacts that provided untold insight into our planet and our civilization’s past, went up in smoke. In the months since the flames were extinguished, researchers have only managed to recover a […]
There are dozens of free "peoplefinder" sites that buy up commercial databases and combine them with other sources to make your home address searchable. You can find instances where this has happened to you by googling your name and home address, and then you can google the removal forms for each of the services and […]
For the true audio enthusiast, there’s a lot of difference between putting on some songs “for background music” and a true listening experience. For the latter, there’s nothing like a pair of sturdy headphones and the powerful speakers that come with them. And the wireless variety doesn’t get much more powerful than the TREBLAB Z2 […]
Digital or analog, there’s a path of least resistance for any project. Finding that path is what the Agile methodology is all about, which is why proficiency in it is a must for any project management position – and the paycheck that comes with it. And the quickest path to learning Agile? The Agile Project […]
Everybody’s flown a paper airplane. But what if you could fly on a paper airplane? Until we invent shrink-ray technology, the PowerUp X FPV Video Paper Airplane Kit will have to do – but it’s as fun as that sounds and more. The original version of this creative toy added drone tech to the old, […]
