#Wi-fi Everywhere May Let You Roam Free From Your Mobile Carrier To get the most out of your smartphone do need you really a cellphone plan?
when he spent a month relying only on Wi-fi networks for his mobile data and voice needs.
and adjustments to your routine you can get almost as much out of your smartphone with a monthly bill of $0.
The frustrations of the switch were relatively minimal Knutson told NPR's Robert Siegel in an interview conducted over Skype.
but with Wi-fi they're hotspots Knutson said. So you can't walk down the street
while doing the Wi-fi only plan because the signals just don't carry far enough to cover you over long distances.
if you're offline companies stitching individual hotspots into networks and carriers with cheap plans that rely on Wi-fi first
and roam on the network of a cellular provider such as Sprint as a backup. Google on Monday announced its own plans to enter the cellphone carrier market The New york times reported:
The ease of his transition and the burgeoning competition could pose serious issues for the industry Knutson writes:
Knutson told Siegel that cellphone providers aren't worried about the competition saying there always will be a market for people who will pay money to have connectivity wherever they go

Inside a ground-floor windowless room there's a display that looks exactly like what you'd see out of an air traffic control tower.
But instead of windows these are actually screens. And the airport you're looking at isn't the one in Sundsvall.
And a problem landing an airplane is far more consequential than a laptop freezing up. Backman says when he saw the first mockup of this technology in 2004 he was dubious.

"But recent advancements in the field of computer-based modeling may make it easier someday for good surgeons to be great.
One such technology comes from Dassault systèmes, a French company that specializes in 3-D software to help engineers who design cars

"Doctors wear 3-D glasses and use a joystick to zoom in to a ventricle or valve,
The software is free to organizations that agree to conduct research and share their findings with the project.
"Challenges to greater adoption of computer-modeling include a lack of data for some medical conditions,
Internet connections were getting faster, hard drives stored more data in tinier spaces, songs were easier than ever to find and available for little or no money.
Every year, the new version of Apple's ipod, first introduced in 2001 with a now-adorable 5gb of storage space, held thousands upon thousands more songs.

Apple stands to gain plenty by luring its hundreds of millions of users to a subscription-based streaming service,
The transition will speed surely the decline of the single-song download, and itunes, the world's largest music store, will feel that pain acutely.
Apple's entry into the market isn't the signal that the world is ready for streaming music;
when itunes will launch its attack on established services like Spotify, we're going to examine the world of streaming music that is upon us in a series called Streaming At The Tipping Point.
The recording industry's fight against that principle took on the form of invasive digital rights management software, advertising campaigns, threats and lawsuits.
Every time you click play on a streaming service, from Pandora to Youtube to Spotify, you're licensing the right to listen to the song in that particular moment,

#Researchers develop new Algorithm to empower Robots to Learn like Humans New algorithms enable robots to learn motor tasks through trial and error, like humans.
The algorithm gives rise to a new branch of artificial intelligence, known as deep learning. The researchers chose Berkeley Robot for the Elimination of Tedious Tasks (BRETT) to take up a challenge of dealing with a relatively promising form of artificial intelligence called deep structured learning.
The researchers have claimed that smaller amount of pre-programming is required when the algorithm is used in the robot.
Also, it provides the capacity to work outside controlled environments like medical centers factories or laboratories.
A team led by Pieter Abbeel, an associate professor in the campus electrical engineering and computer sciences department, developed the new algorithm.
Abbeel said the best thing about the technique is that it rids the need of reprogramming
Use of the algorithm is seen currently in voice recognition software, such as the iphone's Siri
#New Algorithm enables Robot to Learn through Trial and error UC Berkeley's BRETT (Berkeley Robot for the Elimination of Tedious Tasks) is capable of learning through trial and error, like humans.
New algorithms developed by researchers empower the robot to master tasks through trial and error, ridding the need of pre-programming.
Among many tasks, it can perform is assembling a toy, and the best thing is it keeps trying figuring out the way to accomplish the task until it finally done.
The researchers are optimistic that the further development of the robotic technology will enable robots to handle lots of data.
The technology gives rise to artificial intelligence to allow robots to do anything their designs Allow for example
New algorithms developed by researchers from UC Berkeley brought this trial and error process to robots. UC Berkeley said in a press release that the technology is a giant leap in the field of artificial intelligence.
The technology enables the robot to perform tasks like putting a clothes hanger on a rack without feeding details into it about its surrounding. he key is that
The exact same software, which encodes how the robot can learn, was used to allow the robot to learn all the different tasks we gave it said UC Berkeley Professor Pieter Abbeel.

#Amazon Turns to Artificiai Intelligence to Combat Fake Reviews Amazon is using artificial intelligence to combat fake product reviews
It is employing a new AI machine-learning system that the online retailer built in-house to boost the prominence and weight of verified customer purchase reviews, those marked as helpful by other users and newer, more up-to-date critiques
on its site. The system will bring what Amazon thinks are more accurate reviews to the top
The algorithm will improve over time, Amazon told technology site Cnet. Its first effects may not be visible for some time as the work only began on Friday.
Customer reviews have become the cornerstone of trust in the online shopping world. Where users cannot see in person what the products are like before they buy them,
the ratings and reviews of users who have bought supposedly them before can make or break a product.
Can you trust that five star review? That means marketers have taken to attempting to influence star ratings,
especially in the initial stages of a product going on sale on any particular site. They post fake, inflationary reviews or pay users to do so on their behalf.
The practice known as stroturfingfake grassroots campaigns is widespread across a variety of sites and services.
Amazon, as one of the world largest online retailers, is a significant target. But Amazon also indicated that its system will be capable of differentiating between original products
The reviews of the fixed product will be used to outweigh older ones of the broken product to create a more consistent and useful rating of the product users would receive now.
To maintain user trust, more and more sites that host user reviews will have to implement smarter and smarter systems to prevent abuse.
Amazon AI-based system will be watched closely by both competitors and creators. If it works it could end astroturfing as we know it today
