NASA on Saturday scrubbed the launch of a sounding rocket which will release blue-green and red artificial clouds. “Launch scrubbed because of boats in the impact area for the second stage motor. We will try again Sunday, June 4,” NASA’s Wallops Flight Facility announced on its Facebook page. The launch window is 4:26 to 4:41 a.m.EDT (1:56-2.11 p.m India time).

The launch of the Terrier-Improved Malemute sounding rocket testing a new deployment system to support space studies was originally scheduled for May 31, but it was subsequently delayed. “Clear skies are required at one of the ground stations to view blue-green and red artificial clouds that will be produced as part of the test. These artificial clouds may be seen from New York to North Carolina,” NASA earlier said.

The rocket will eject 10 canisters about the size of a soft drink can between 10 to 20 kms from the rocket’s main payload, and these containers will release the vapour between 4 and 5.5 minutes after launch.These clouds or vapour tracers allow scientists on the ground to visually track particle motions in space.

The development of the multi-canister or ampule ejection system will allow scientists to gather information over a much larger area than previously allowed when deploying the vapour just from the main payload.Ground cameras will be stationed at Wallops and in Duck, North Carolina, to view the vapour tracers. “The vapour tracers are formed through the interaction of barium, strontium and cupric-oxide. The tracers will be released at altitudes 96 to 124 miles high and pose absolutely no hazard to residents along the mid-Atlantic coast,” NASA said

Sounding rockets take their name from the nautical term “to sound,” which means to take measurements. The flight of a sounding rocket is short-lived, and has a parabolic trajectory — the shape of a frown. The total flight time for the current mission is expected to be about eight minutes. The payload will land in the Atlantic Ocean about 90 miles from Wallops Island and will not be recovered.

Facebook Developing Artificial Intelligence to Flag Offensive Live Videos

Facebook Developing Artificial Intelligence to Flag Offensive Live Videos

Facebook Developing Artificial Intelligence to Flag Offensive Live Videos
Facebook Inc is working on automatically flagging offensive material in live video streams, building on a growing effort to use artificial intelligence to monitor content, said Joaquin Candela, the company’s director of applied machine learning.

The social media company has been embroiled in a number of content moderation controversies this year, from facing international outcry after removing an iconic Vietnam War photo due to nudity, to allowing the spread of fake news on its site.

Facebook has historically relied mostly on users to report offensive posts, which are then checked by Facebook employees against company “community standards.” Decisions on especially thorny content issues that might require policy changes are made by top executives at the company.
Candela told reporters that Facebook increasingly was using artificial intelligence to find offensive material. It is “an algorithm that detects nudity, violence, or any of the things that are not according to our policies,” he said.

The company already had been working on using automation to flag extremist video content, as Reuters reported in June.

Now the automated system also is being tested on Facebook Live, the streaming video service for users to broadcast live video.

Using artificial intelligence to flag live video is still at the research stage, and has two challenges, Candela said. “One, your computer vision algorithm has to be fast, and I think we can push there, and the other one is you need to prioritize things in the right way so that a human looks at it, an expert who understands our policies, and takes it down.”
Facebook said it also uses automation to process the tens of millions of reports it gets each week, to recognize duplicate reports and route the flagged content to reviewers with the appropriate subject matter expertise.

Chief Executive Officer Mark Zuckerberg in November said Facebook would turn to automation as part of a plan to identify fake news. Ahead of the November 8 US election, Facebook users saw fake news reports erroneously alleging that Pope Francis endorsed Donald Trump and that a federal agent who had been investigating Democratic candidate Hillary Clinton was found dead.

However, determining whether a particular comment is hateful or bullying, for example, requires context, the company said.

Yann LeCun, Facebook’s director of AI research, declined to comment on using AI to detect fake news, but said in general news feed improvements provoked questions of tradeoffs between filtering and censorship, freedom of expressions and decency and truthfulness.

“These are questions that go way beyond whether we can develop AI,” said LeCun. “Tradeoffs that I’m not well placed to determine.”

Google Announces Artificial Intelligence Group for Google Cloud

Google Announces Artificial Intelligence Group for Google Cloud
Alphabet’s Google announced the formation of an artificial intelligence group for Google Cloud, the tech company’s latest gambit to increase its market share in the lucrative cloud computing business.

Diane Greene, who leads Google’s cloud business, announced the team at an event at the company’s facilities in San Francisco. The group will be led by Fei-Fei Li, an artificial intelligence professor at Stanford University, and researcher Jia Li.

“What really attracted these two people to come and be in Google Cloud is a chance to democratize machine learning and artificial intelligence,” Greene said.

In the meanwhile, Google delivered a vote of confidence in London’s future as a technological hub after the Brexit vote on Tuesday by announcing plans for a new building in the King’s Cross area of the city that will house thousands of extra engineers.

Google’s Chief Executive Sundar Pichai said computer science had a great future in Britain, citing the talent pool, educational institutions, and passion for innovation present in the country.
“That’s why we are investing in London in both engineering talent and infrastructure,” he said.
The 10-storey building, Google’s first wholly owned and designed outside the United States, will increase its presence in King’s Cross to more than 1 million square feet, enough for more than 7,000 employees in total, the company said.

Google has 5,700 employees and contractors in the UK, including about 2,000 engineers housed in the recently opened building in King’s Cross where Pichai announced the expansion.

Twitter Buys Artificial Intelligence Firm Magic Pony

Twitter Buys Artificial Intelligence Firm Magic Pony

HIGHLIGHTS

  • Magic Pony’s team will be joining Twitter Cortex.
  • Magic Pony includes scientists with expertise in machine learning.
  • Terms of the deal were not disclosed.

Twitter said Monday it was acquiring British-based artificial intelligence startup Magic Pony to bolster its capacity for analysis of visual content.

Magic Pony’s technology, based on research to create algorithms that can understand the features of imagery “will be used to enhance our strength in live and video and opens up a whole lot of exciting creative possibilities forTwitter,” said Twitter co-founder and chief executive Jack Dorsey in a blog post.

“Machine learning is increasingly at the core of everything we build at Twitter. It’s powering much of the work we’re doing to make it easier to create, share, and discover the very best content so that every time you open Twitter you’re immersed in the most relevant news, stories, and events for you.”

Terms of the deal were not disclosed.

The move comes with Twitter struggling to grow its user base and achieve profitability amid disappointment in the platform after a long-awaited 2013 initial public offering.

Rob Bishop, Magic Pony’s CEO and co-founder, said joining forces with Twitter “gives us the opportunity to bring the benefits of that research to hundreds of millions of people around the world, and allows Magic Pony to contribute to better quality viewing experiences on Twitter.”

Magic Pony team includes scientists with expertise across computer vision, machine learning, high-performance computing, and computational neuroscience.

Bishop will be based out of Twitter’s headquarters in San Francisco, and co-founder Zehan Wang and the other members will join Twitter’s London office, according to a statement.

Magic Pony’s team will be joining Twitter Cortex, a team of engineers, data scientists, and machine learning researchers. Twitter’s other machine learning acquisitions include Madbits in July 2014 and Whetlab in June 2015.
