MessageToEagle.com - Navigating our way down the street is something most of us take for granted; we seem to recognize cars,
other people, trees and lampposts instantaneously and without much thought.
In fact, visually interpreting our environment as
quickly as we do is an astonishing feat requiring an enormous number of computations—which is just one reason that coming up
with a computer-driven system that can mimic the human brain in visually recognizing objects has proven so difficult.
Now Eugenio Culurciello of Yale’s School of Engineering & Applied Science has developed a supercomputer based on the human
visual system that operates much more quickly and efficiently than ever before.
Dubbed NeuFlow, the system takes its inspiration from the mammalian visual system, mimicking its neural network to quickly
interpret the world around it. Culurciello presented the results Sept. 15 at the High Performance Embedded Computing (HPEC) workshop in Boston, Mass.
The system uses complex vision algorithms developed by Yann LeCun at New York University to run large neural networks for
synthetic vision applications. One idea—the one Culurciello and LeCun are focusing on, is a system that would allow cars to drive themselves.
In order to be able to recognize the various objects encountered on the road—such as other cars, people, stoplights,
sidewalks, not to mention the road itself—NeuFlow processes tens of megapixel images in real time.

The system is also extremely efficient, simultaneously running more than 100 billion operations per second using only a few watts (that’s less than the power a cell phone uses) to accomplish what it takes bench-top computers with multiple graphic processors more than 300 watts to achieve.
“One of our first prototypes of this system is already capable of outperforming graphic processors on vision tasks,” Culurciello said.
Culurciello embedded the supercomputer on a single chip, making the system much smaller, yet more powerful and efficient, than full-scale computers.
“The complete system is going to be no bigger than a wallet, so it could easily be embedded in cars and other places,” Culurciello said.
Beyond the autonomous car navigation, the system could be used to improve robot navigation into dangerous or difficult-to-reach locations, to provide 360-degree synthetic vision for soldiers in combat situations, or in assisted living situations where it could be used to monitor motion and call for help should an elderly person fall, for example.

Abnormal Star Discovered In The 'Forbidden Zone'
A team of astrophysicists from Germany, France and Italy have discovered in the constellation Leo is an old star.
The star's existence raised at once many questions for scientists.
The object is definitely not as its "contemporaries" that appeared immediately after the Big Bang event.
Astrophysicist Resolves Paradox With Radio Millisecond Pulsars
Celestial objects known as pulsars are still full of secrets. It is takes time and many efforts to learn all their secrets. Previous studies reached
the paradoxical conclusion that some millisecond pulsars are even older than the universe itself. It was time to resolve this paradox.
The Eyes Of A Future Alien Astronomer - What Will They See?
Have you ever wondered what the Universe will look like for a future alien astronomer?
It will in fact be entirely different from what it is today.
One trillion years from now, an alien astronomer in our galaxy will have great difficulties figuring out how the universe began.
The Milky Way will have merged with the Andromeda galaxy to form the Milkomeda galaxy. Many of its stars, including our Sun, will have burned out.
Violent Dragon Clash Billions Of Years Ago
NGC 5907 is sometimes called the "Splinter" or Knife Edge Galaxy because of its unusual appearance.
It is a spiral galaxy lying in the Dragon constellation,
about 40 million light-years from Earth that could have been formed through a gigantic collision of galaxies, 8 to 9 billion years ago.
