has a terrific overview of the perpetual "virtual lineup
," where half of all American adults "are enrolled in unregulated facial recognition networks used by state and local law enforcement agencies."
Much of his article centers on research being done
by Georgetown's Center on Privacy & Technology:
Studies of racial bias in face recognition algorithms are few and far between. The research that has been done, however, suggests that these systems do, in fact, show signs of bias. The most prominent study, co-authored by an FBI expert, found that several leading algorithms performed worse on African Americans, women, and young adults than on Caucasians, men, and older people, respectively. In interviews, we were surprised to find that two major face recognition companies did not test their algorithms for racial bias.
The algorithmic bias has been described as “the coded gaze” by Joy Buolamwini, an MIT Media Lab graduate student, in a nod to the literary and sociological term “the white gaze,” which describes seeing the world from the perspective of a white person and assuming, always, that your audience is white.
Buolamwini, a Fulbright Fellow and two-time recipient of NASA’s Astronaut Scholarship, launched the Algorithmic Justice League last year to highlight biases in machine learning. “Why isn’t my face being detected? We have to look at how we give machines sight,” she said in a TED Talk late last year. “Computer vision uses machine-learning techniques to do facial recognition. You create a training set with examples of faces. However, if the training sets aren’t really that diverse, any face that deviates too much from the established norm will be harder to detect.”
Here's her talk on algorithmic bias:
• Facial Recognition Technology Is Both Biased and Understudied (Undark via TED)
Scientists combined multiple imaging technologies to deliver an unprecedented 3D view inside the body of crawling cancer cells, spinal cord circuit development, and immune cells traveling within a zebrafish (above). Nobel laureate Eric Betzig and his colleagues at the Howard Hughes Medical Institute integrate a technology called lattice light sheet microscopy with adaptive optics resulting […]
Landru79 created this spectacular GIF from images captured in 2016 on the surface of Comet 67P/Churyumov–Gerasimenko by the European Space Agency lander Philae deployed by the Rosetta probe. The video is significantly sped up, compressing 25 minutes into a few seconds of intense action. But what exactly are we looking at in this pandemonium? From […]
Using DNA to store digital data has been a classic forecast in infotech futurism for more than two decades. The basic concept is that you could synthesize strands of DNA encoded with digital information and then decode it with DNA sequencing techniques. While several amazing experiments have demonstrated that DNA data storage is possible, it’s […]
Our computers are home to a myriad of files and documents, many of which contain sensitive information. While storing this data on your computer is convenient, it’s not exactly safe, and with news headlines highlighting data leaks and ransomware attacks on what seems like a daily basis, moving them to a safer location is a […]
Total versatility isn’t something you’d typically find in a telescope. While magnification tech has come a long way, most telescopes are designed to either gaze upon the stars or view the landscapes beneath them. The Omegon Maksutov Telescope MightyMak 60 lets you do both, and thanks to its compact design, you can easily incorporate some sightseeing into […]
The web is an invaluable tool for connecting small businesses with their target audiences. However, when it comes to building a website and marketing online, the learning curve can be steep if you’re doing it on your own. The WordPress Essentials Lifetime Bundle can help you out by getting you up to speed with the platform […]
