Report: US AI development is concentrated in 15 metro areas


Last week, the Brookings Institution published an examination of the "extent, location, and concentration" of AI activity in 400 US metro areas, hailing it as the "next great'general purpose technology,'" with the power to spur economic growth. Key takeaways: Although it already feels like AI is everywhere, the tech is still in its early days--and in the US, AI development and commercialization is mega-concentrated in a handful of mostly coastal locales. But, but, but: Brookings also identified 13 other metro areas with "above-average involvement" in AI, including hubs you may have seen coming--New York, Boston, Seattle, Los Angeles, Washington, D.C., San Diego, Austin, Texas, and Raleigh, North Carolina--as well as smaller metro areas like Boulder, Colorado, Lincoln, Nebraska, Santa Cruz, California, Santa Maria-Santa Barbara, California, and Santa Fe, New Mexico. Zoom out: The above 15 metro areas account for two-thirds of AI activity nationwide--and for that matter, more than 50% of the areas Brookings looked at make up just 5% of AI activity, Wired reported.

Deep Learning-based Compressive Beam Alignment in mmWave Vehicular Systems Artificial Intelligence

Millimeter wave vehicular channels exhibit structure that can be exploited for beam alignment with fewer channel measurements compared to exhaustive beam search. With fixed layouts of roadside buildings and regular vehicular moving trajectory, the dominant path directions of channels will likely be among a subset of beam directions instead of distributing randomly over the whole beamspace. In this paper, we propose a deep learning-based technique to design a structured compressed sensing (CS) matrix that is well suited to the underlying channel distribution for mmWave vehicular beam alignment. The proposed approach leverages both sparsity and the particular spatial structure that appears in vehicular channels. We model the compressive channel acquisition by a two-dimensional (2D) convolutional layer followed by dropout. We incorporate the low-resolution phase shifter constraint during neural network training by using projected gradient descent for weight updates. Furthermore, we exploit channel spectral structure to optimize the power allocated for different subcarriers. Simulations indicate that our deep learningbased approach achieves better beam alignment than standard CS techniques which use random phase shift-based design. Numerical experiments also show that one single subcarrier is sufficient to provide necessary information for beam alignment. Millimeter-wave (mmWave) vehicular communication enables massive sensor data sharing and various emerging applications related to safety, traffic efficiency and infotainment [2]-[4].

How Startups Can Use AI-Powered Tools to Scale Up


What comes to your mind when you think of "artificial intelligence?" And you are right, sort of. AI is capable of doing all those things, plus it's capable of revolutionizing the business landscape. "For many people, artificial intelligence, or AI, is a mere concept, something that will happen in the future. But, in reality, AI has already become a part of mainstream businesses", says Michael Georgio, CMO of Imaginovation, a Raleigh, N.C.-based AI development company.

Artificial Intelligence and Machine Learning Won't Eliminate Entirely the Need for Human Workers


Artificial intelligence (AI), Machine Learning (ML) and automation will create more jobs than they eliminate. And the people employed in the new work environment must bring higher thinking skills, as well as social and emotional intelligence as technologists, to their workplaces and positions. In the Technologist Talk podcast series, Charles Eaton, Creating IT Futures CEO and CompTIA's executive vice president for social innovation, has referred to this workforce evolution as becoming "technologists, not just technicians." That was the key message shared by Diya Wynn, global readiness lead at Amazon Web Services Inc., during her breakout session at today's Women In Technology Summit Southeast (WITS) held in Raleigh, North Carolina. WITS is the only technical conference that features all women speakers and has programming specifically designed for women technologists working in technical and non-technical roles.

Drone Delivery Is One Step Closer To Reality

Matternet CEO Andreas Raptopoulos walks next to an operator carrying a drone used to deliver medical specimens after a flight in March at WakeMed Hospital in Raleigh, N.C. Underneath it is a metal box -- smaller than a shoebox -- with vials of blood samples inside of it that are now heading across the campus to the lab for analysis, guided by a drone operator on the ground. "This facility happens to be across a very busy road from our main campus hospital," says Stuart Ginn, an ENT surgeon and medical director of innovations at WakeMed. But when taken by carrier on foot or by car, he says "the logistics of getting those samples across often resulted in about a 45-minute time of delivery."

UPS has won approval to run the first drone delivery airline in the US


It will still be a while before you are able to order drone-delivered packages, however. The news: The Federal Aviation Administration has granted UPS's drone business a Part 135 certification, meaning it is treated as a full-fledged airline, able to operate as many drones in as many locations as it wishes (although there are a lot of obstacles and caveats before that can happen in reality). UPS has dubbed its new drone airline "UPS Flight Forward," and it's the first in the US to gain official recognition. Currently: UPS has been providing a drone delivery service at the WakeMed hospital and campus in Raleigh, North Carolina, since March, moving medical samples around the site about 10 times a day. This new certification means UPS can expand beyond this site.

UPS receives government approval for drone delivery - beating out Amazon and Alphabet

Daily Mail - Science & tech

UPS has become the first drone delivery service to receive full approval from the Federal Aviation Administration. The company's program, called Flight Forward, is operated in partnership with Matternet, which provides drone logistics networking company in Mountain View, California. Previously, UPS's pilots were only allowed to fly the drones within line of sight, but the FAA approval means they'll be able to significantly expand their delivery range. 'This is history in the making, and we aren't done yet,' said David Abney, UPS chief executive officer in a statement. UPS's Flight Forward drone delivery program is the first to earn full approval by the FAA (pictured one of the drones they will use in the program) The program's currently deployed in Raleigh, North Carolina, where UPS's drones have made more than 1,000 flights carrying deliveries around the WakeMed Health & Hospitals campus.

Inside Instagram's War on Bullying

TIME - Tech

Ethan Cohen tried to laugh off his first experience with bullying on Instagram. Like many kids his age, the Raleigh, N.C., teen eagerly joined the platform in middle school, and one day he discovered fellow students snickering at an account. The feed was dedicated to jeers about what appeared to be a prominent muscle in his neck. One post compared it to the Great Wall of China. Another suggested "systems of equations" could be done on its size. To friends, he dismissed it as a dumb prank, but privately he was distressed. Someone was tailing him and posting mocking pictures for all to see. "The anonymity of it was freaky," says Cohen, now 18. He reported the account multiple times to Instagram.

UPS behind first regular commercial drone delivery in America

Daily Mail - Science & tech

UPS will leverage drones to deliver medical samples in the first FAA-backed and continuous commercial deployment of drone technology in America. According to UPS, an autonomous drone -- Matternet's M2 quadcopter -- will travel between locations at WakeMed's campus in Raleigh, North Carolina, flying distances of up to 12.8 miles along a fixed, pre-determined route. Currently, the samples are delivered on the ground via courier cars, says UPS, making the shipments susceptible to road traffic. The use of drones will both increase efficiency and lower costs, the company says. Samples are loaded onto the drone which then flies a predetermined route to a landing pad located within the hospital.
