Toronto, December 2, 2016: Machine learning — a powerful tool used for a variety of tasks in modern life, from fraud detection and sorting spam in Google, to making movie recommendations on Netflix — can help scientists determine whether planetary systems are stable or not, a study says.

“Machine learning offers a powerful way to tackle a problem in astrophysics, and that’s predicting whether planetary systems are stable,” said study lead author Dan Tamayo from the University of Toronto Scarborough in Canada.

Machine learning is a form of artificial intelligence that gives computers the ability to learn without having to be constantly programmed for a specific task. The benefit is that it can teach computers to learn and change when exposed to new data, not to mention it’s also very efficient.

The researchers found that the same class of algorithms used by Google and Netflix can also tell us if distant planetary systems are stable or not.

The method developed by Tamayo and his team is 1,000 times faster than traditional methods in predicting stability.

“In the past we’ve been hamstrung in trying to figure out whether planetary systems are stable by methods that couldn’t handle the amount of data we were throwing at it,” Tamayo said.

It’s important to know whether planetary systems are stable or not because it can tell us a great deal about how these systems formed. It can also offer valuable new information about exoplanets that is not offered by current methods of observation.

There are several current methods of detecting exoplanets that provide information such as the size of the planet and its orbital period, but they may not provide the planet’s mass or how elliptical their orbit is, which are all factors that affect stability, Tamayo noted.

The method developed by Tamayo and his team was published online in the Astrophysical Journal Letters.

“What’s encouraging is that our findings tell us that investing weeks of computation to train machine learning models is worth it because not only is this tool accurate, it also works much faster,” he added.

It may also come in handy when analysing data from NASA’s Transiting Exoplanet Survey Satellite (TESS) set to launch next year. The two-year mission will focus on discovering new exoplanets by focusing on the brightest stars near our solar system.

“It could be a useful tool because predicting stability would allow us to learn more about the system, from the upper limits of mass to the eccentricities of these planets,” Tamayo said. (IANS)

New Delhi, October 11, 2017 : Google’s digital payment app ‘Tez’ that was launched in India on September 18 has been downloaded five million times on Play Store.

Within 24 hours of ‘Tez’ being launched, Google saw nearly 1.8 crore gross merchandise volume (GMV) done with over four lakh active users.

Built on the Indian government-supported Unified Payments Interface (UPI), Tez allows users, free of charge, to make small or big payments straight from their bank accounts.

According to the National Payment Corporation of India (NPCI), the number of transactions on UPI has crossed three crore in September.

The number of transactions on UPI platform increased to 3.07 crore in September as against 1.66 crore in August — an increase of 85.32 per cent.

Of the 3.07 crore transactions, BHIM’s share was 76.03 lakh — a market share of nearly 24.7 per cent.

“Tez” app works in partnership with four Banks — Axis Bank, HDFC Bank, ICICI Bank and State Bank of India — to facilitate the processing of payments across over 50 UPI-enabled banks.

The app was built for India, working on the vast majority of the country’s smartphones and is available in English and seven Indian languages — Hindi, Bengali, Gujarati, Kannada, Marathi, Tamil and Telugu. (IANS)

Chinese internet service providers started blocking access to WhatsApp.

San Francisco, Sep 26 (IANS) Instant messaging service WhatsApp has been largely blocked in China, the media reported.

The Open Observatory of Network Interference (OONI), a global observation network for detecting censorship, surveillance and traffic manipulation, suggested on Monday night that Chinese internet service providers started blocking access to WhatsApp on September 23, reports CNN.

Public reports on Twitter indicated that WhatsApp, which is owned by the US-based social media giant Facebook, became inaccessible for some people on September 19.

Over the last few months, there were a number of WhatsApp disruptions in China.

However, WhatsApp has not made an official announcement on the development.

China has already blocked access to a number of internet companies, including Facebook, Instagram, Twitter and Google.

Some people access these services through virtual private networks (VPN), or with tools that disguise internet traffic to circumvent censorship. But the Chinese government has launched a crack down on VPNs this year.

According to Timothy Heath, senior international defence research analyst at the RAND Corporation, the Chinese government does not like that WhatsApp uses strong encryption.

“The government wants to monitor internet communications, and therefore it’s trying to steer its people to use technology that can be accessed and monitored by the government,” Heath told CNN.

Earlier this month, WeChat, a popular chat service in China, notified users of its policies to comply with government requests for information. (ians)

A Step Towards Digital India- Google Launches Digital Payment App ‘Tez’ in India

Google launched Tez app

New Delhi, Sep 20, 2017: A day after Google launched its new digital payment app “Tez” in India, the company’s Indian-born CEO Sundar Pichai on Tuesday tweeted it will help India move closer to digital transformation.

“We hope that the launch of @TezByGoogle will help take India one step closer to your vision of @_DigitalIndia,” Pichai tweeted.

Finance Minister Arun Jaitley who launched the app here had said the idea of “Tez” was discussed by Pichai in January, just after demonetisation.

“Google saw a great potential in Indian economy and businesses,” Jaitley said, adding that Google’s new digital payments app over the next few months was likely to make major advances in digital transaction volumes.

Built on the Indian government-supported Unified Payments Interface (UPI), Tez allows users, free of charge, to make small or big payments straight from their bank accounts.

The app was built for India, working on the vast majority of the country’s smartphones and available in English and seven Indian languages (Hindi, Bengali, Gujarati, Kannada, Marathi, Tamil and Telugu).

The app works in partnership with four Banks — Axis Bank, HDFC Bank, ICICI Bank and State Bank of India — to facilitate the processing of payments across over 50 UPI-enabled banks.

According to D D Mishra, Research Director, Gartner, Tez provides promising features which are in-line with the requirements.

“It is too early to say whether it can be a game changer as evolution in this business is going to continue, but yes it has the capabilities to bring some disruption as of now,” Mishra said in a statement.

Moreover, Google’s information about an individual’s preferences can play a good role in enabling the business to know their preferences and provide offers with interesting options.

“The mobile wallet industry too is evolving and we are at an interesting stage in this competition. Eventually, UPI payments will have an upper hand if it continues to remain free and provide better security, convenience and add more Value Added Services,” Mishra informed. (IANS)
