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.

Sidewalk Labs is the division of Alphabet/Google that builds "smart city" technology; their most ambitious project to date is a massive privatised city-within-a-city planned for Toronto's lakeshore -- a project that received secretly approval to be much larger than was announced, a fact that Sidewalk lied about.
This week, Keep Internet Devices Safe Act was gutted by the Illinois senate: it would have allowed people sue manufacturers if they determined that a device had engaged in remote recording without notifying its owner.
This week, thousands of googlers and many others (including me) signed an open letter objecting to the inclusion of Heritage Foundation president Kay Coles James on the company's Advanced Technology External Advisory Council (ATEAC), on the the grounds that James had frequently evinced viciously transphobic, racist, anti-immigrant sentiments.

Ever wonder if you’re cleaning your teeth well enough? If your last dentist visit has you getting a little more thorough about oral care, it might be time to save yourself some guesswork. A lot of electric toothbrushes promise deep cleaning, but there’s a Platinum Sonic Toothbrush that has power plus the simple but effective […]
The digital age is well and truly upon us, but let’s not forget there’s a load of free TV content floating literally over our heads. No, we’re not talking about the internet. Signals from major broadcast networks are still gratis for anyone who can pick them up with an antenna. And before you envision those […]
