Google uses Neural networks to decipher numbers in Images by robots

Google researchers have developed technology that nearly perfectly deciphers the distorted combinations of numbers and letters commonly used on the internet to test whether or not someone is human.
Ian J. Goodfellow, Yaroslav Bulatov, Julian Ibarz, Sacha Arnoud, and Vinay Shet, set out todevelop a more accurate method to identify numbers in images taken for Google Street View. Their model identified, with better than 90 per cent accuracy, tens of millions of numbers contained in Street View images taken in a dozen countries.
Using the model in conjunction with Google's infrastructure, it takes less than an hour to transcribe all the views of street numbers in France.
The technology was also pitted against the hardest category of the character-blurring forms known as CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart). It is based on the concept of the Turing test, which is a standard way to assess whether a human can identify, via verbal exchanges, whether a respondent is human or a computer.
Tested against reCAPTCHA, Google's own variation, Mr Goodfellow and his team achieved near perfect results.
"Today, distorted text in reCAPTCHA serves increasingly as a medium to capture user engagements rather than a reverse Turing in and of itself," the researchers wrote. "These results do, however, indicate that the utility of distorted text as a reverse Turing test by itself is significantly diminished."
Google's technology uses a system called DistBelief, which leverages a scientific concept called convolutional neural networks. Inspired by biology, these neuron structures mimic the complex arrangement of cells within the part of the brain that interprets images.

How to use home loans most effectively for tax benefits

1) Deduction on interest: If you are paying EMIs for a home loan you took to buy a house, the interest component in the EMI can be claimed as deduction. You must be both an owner and a co-borrower (in the loan) to claim tax benefits. This deduction can be claimed starting the year in which the construction of the house is completed. Suppose the construction of your house was completed on August 30, 2014, you can claim deduction for interest for the entire 12 months in financial year 2014-15. So every year a maximum of Rs. 2 lakh can be claimed for a house that you use for your own residence. If your house is rented, the entire interest for the year can be claimed as deduction. The interest payments for the year shall result in a loss under the head 'income from house property'. This loss can be adjusted against in the same year against other heads of income in your income tax return including salary. Therefore, it reduces your total taxable income and the tax you pay thereon. A...

Intellectual battle against ISIS as important as Military: Sheikh Makhtoum of Dubai

The global financial crisis taught the world how profoundly interdependent our economies have become. In today's crisis of extremism, we must recognize that we are just as interdependent for our security, as is clear in the current struggle to defeat ISIS. Mohammed bin Rashid Al Maktoum, VP and prime minister of the UAE, ruler of Dubai If we are to prevent ISIS from teaching us this lesson the hard way, we must acknowledge that we cannot extinguish the fires of fanaticism by force alone. The world must unite behind a holistic drive to discredit the ideology that gives extremists their power, and to restore hope and dignity to those whom they would recruit. ISIS certainly can – and will – be defeated militarily by the international coalition that is now assembling and which the UAE is actively supporting. But military containment is only a partial solution. Lasting peace requires three other ingredients: winning the battle of ideas; upgrading weak governance; and ...
