Why Quantum "Clippers" Will Distribute Entanglement Across The Oceans - 0 views

  •  
    Quantum internet will enable perfectly secure communications, but the technology and means to build the required quantum memories and routers are still many years distant. The proposal here is to store qubits and send them in containers over the oceans. Researchers claim that it is possible to send information at bandwidths measured in teraahertz outperforming the predictions of a quantum router internet. It can be thought in space systems as well. Then the problem is still for how long are we able to store a qubit, without dephasing... PS: As a curiosity, you can find a very interesting book about containers and how in some way they changed our world: Mark Levinson's book 'The Box' http://press.princeton.edu/titles/9383.html Maybe they will do it again

physicists explain what AI researchers are actually doing - 5 views

  •  
    love this one ... it seems to take physicist to explain to the AI crowd what they are actually doing ... Deep learning is a broad set of techniques that uses multiple layers of representation to automatically learn relevant features directly from structured data. Recently, such techniques have yielded record-breaking results on a diverse set of difficult machine learning tasks in computer vision, speech recognition, and natural language processing. Despite the enormous success of deep learning, relatively little is understood theoretically about why these techniques are so successful at feature learning and compression. Here, we show that deep learning is intimately related to one of the most important and successful techniques in theoretical physics, the renormalization group (RG). RG is an iterative coarse-graining scheme that allows for the extraction of relevant features (i.e. operators) as a physical system is examined at different length scales. We construct an exact mapping from the variational renormalization group, first introduced by Kadanoff, and deep learning architectures based on Restricted Boltzmann Machines (RBMs). We illustrate these ideas using the nearest-neighbor Ising Model in one and two-dimensions. Our results suggests that deep learning algorithms may be employing a generalized RG-like scheme to learn relevant features from data.

Why Xbox Kinect didn't take off - Business Insider - 2 views

  •  
    Interesting read!
  •  
    it got some interesting viewpoitns from a game/marketing point of view but to say that Kinect2 was only a marginal improvement over the first one is only true if you think about games. For robots it is a huge step forward!

Why Is It So Hard to Predict the Future? - The Atlantic - 1 views

  • The Peculiar Blindness of Experts Credentialed authorities are comically bad at predicting the future. But reliable forecasting is possible.
  • The result: The experts were, by and large, horrific forecasters. Their areas of specialty, years of experience, and (for some) access to classified information made no difference. They were bad at short-term forecasting and bad at long-term forecasting. They were bad at forecasting in every domain. When experts declared that future events were impossible or nearly impossible, 15 percent of them occurred nonetheless. When they declared events to be a sure thing, more than one-quarter of them failed to transpire. As the Danish proverb warns, “It is difficult to make predictions, especially about the future.”
  • Tetlock and Mellers found that not only were the best forecasters foxy as individuals, but they tended to have qualities that made them particularly effective collaborators. They were “curious about, well, really everything,” as one of the top forecasters told me. They crossed disciplines, and viewed their teammates as sources for learning, rather than peers to be convinced. When those foxes were later grouped into much smaller teams—12 members each—they became even more accurate. They outperformed—by a lot—a group of experienced intelligence analysts with access to classified data.

Google Says the FBI Is Secretly Spying on Some of Its Customers | Threat Level | Wired.com - 3 views

  •  
    not a surprise though still bad to read ....
  •  
    On a side note, it's hilarious to read an article on something repeatedly referred to as being secret...
  •  
    quite self-explanatory described though: "The terrorists apparently would win if Google told you the exact number of times the Federal Bureau of Investigation invoked a secret process to extract data about the media giant's customers. That's why it is unlawful for any record-keeper to disclose it has received a so-called National Security Letter. But under a deal brokered with the President Barack Obama administration, Google on Tuesday published a "range" of times it received National Security Letters demanding it divulge account information to the authorities without warrants. It was the first time a company has ever released data chronicling the volume of National Security Letter requests. National Security Letters allow the government to get detailed information on Americans' finances and communications without oversight from a judge. The FBI has issued hundreds of thousands of NSLs and has even been reprimanded for abusing them. The NSLs are written demands from the FBI that compel internet service providers, credit companies, financial institutions and businesses like Google to hand over confidential records about their customers, such as subscriber information, phone numbers and e-mail addresses, websites visited and more as long as the FBI says the information is "relevant" to an investigation." and ""You'll notice that we're reporting numerical ranges rather than exact numbers. This is to address concerns raised by the FBI, Justice Department and other agencies that releasing exact numbers might reveal information about investigations. We plan to update these figures annually," Richard Salgado, a Google legal director, wrote in a blog post. Salgado was not available for comment. What makes the government's position questionable is that it is required by Congress to disclose the number of times the bureau issues National Security Letters. In 2011, the year with the latest available figures, the FBI issued 16,511 National Sec

Should business be allowed to patent mathematics? - opinion - 18 March 2013 - New Scientist - 1 views

    ridiculous next frontier for patenting ... mathematics!!!!!

    Creating jobs in the 21st century. Banks and insurance companies are firing mathematicians because they follow logic's rules when calculating product costs and rates. However, this work is being shifted since years to the marketing departments. Didn't you know that marketing experts are able to perform complex calculations as well, even improving the equations by adding market developments? Anyway, thousands of mathematicians need a job now, why not in the patent offices?

    Who finds the irony can keep it.

    should I take these as an indication of news from the bankers concerning your business case?

    this would trigger innovation, and kill mathematics! The world is crazy... imagine a mathematician that will have to pay to use a demonstration for his own demonstration... haha. And the interviewed guy in the article say that this would benefit mathematicians !!! what a joke ! And all the schools that will have to pay billions to Euclid's heirs ! This would kill physics too, and all domains that use mathematics as a tool !
