When AI is made by AI, results are impressive - 6 views

    This has been around for over a year. The current trend in deep learning is "deeper is better". But a consequence of this is that for a given network depth, we can only feasibly evaluate a tiny fraction of the "search space" of NN architectures. The current approach to choosing a network architecture is to iteratively add more layers/units and keeping the architecture which gives an increase in the accuracy on some held-out data set i.e. we have the following information: {NN, accuracy}. Clearly, this process can be automated by using the accuracy as a 'signal' to a learning algorithm. The novelty in this work is they use reinforcement learning with a recurrent neural network controller which is trained by a policy gradient - a gradient-based method. Previously, evolutionary algorithms would typically be used.

    In summary, yes, the results are impressive - BUT this was only possible because they had access to Google's resources. An evolutionary approach would probably end up with the same architecture - it would just take longer. This is part of a broader research area in deep learning called 'meta-learning' which seeks to automate all aspects of neural network training.

The Truth About Google X: An Exclusive Look Behind The Secretive Lab's Closed Doors - 4 views

  • Space elevators, teleportation, hoverboards, and driverless cars: The top-secret Google X innovation lab opens up about what it does--and how it thinks.
    Interesting insight indeed, I see quite some overlap with the ACT mantra, athough they have 250 people and an outdoor playground..

    To Teller, this failure-loving lab has simply stepped into the breach. Small companies don't feel they have the resources to take moonshots. Big companies think it'll rattle shareholders. Government leaders believe there's not enough money, or that Congress will characterize a misstep or failure as a scandal. These days, when it comes to Hail Mary innovation, "Everyone thinks it's somebody's else's job," Teller says.

In Head-Hunting, Big Data May Not Be Such a Big Deal - - 1 views

  • Years ago, we did a study to determine whether anyone at Google is particularly good at hiring. We looked at tens of thousands of interviews, and everyone who had done the interviews and what they scored the candidate, and how that person ultimately performed in their job. We found zero relationship. It’s a complete random mess

Google Says the FBI Is Secretly Spying on Some of Its Customers | Threat Level | - 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."


    ""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

  • 1.2 trillion searches.

    146 languages.

    What did the world search for in 2012?

    this is a gold mine :D

    Portugal, a bankrupt country in crisis where the Most Searched How to... is "Como emagrecer" (how to lose weight?).

    Netherlands, where the Most Searched How to... is "Hoe overleef ik" (how do I survive?)

    UK where the most Trending What is... is "What is love?"

    and Italians... please explain how come the top Trending How to... are
    1. Come fare Sesso
    2. Come fare un Clistere

    Respect for Austria though, where the top trending What is... are:
    1. Was ist ACTA
    2. Was ist SOPA

    any other interesting finds?
    From Ghana "What is...?":
    What is a Constitution
    What is Government

    [edit] Some top Science searches in the US: Hemorrhoid, Pregnancy Syndroms. Any potential for Ariadna?

    [edit] ... and finally, for the sake of my shield, top search from Poland in the Music category

Google Begins Testing Its Augmented-Reality Glasses - - 4 views

  • On Wednesday, Google gave people a clearer picture of its secret initiative called Project Glass. The glasses are the company’s first venture into wearable computing.
    this will be big! check the video.
    according to one of the related posts, they'll be on sale already by the end of 2012! Surprising that it's Google and not Apple to come up with this

Google AI Challenge: Ants - 2 views

    "Ants is a multi-player strategy game set on a plot of dirt with water for obstacles and food that randomly drops. Each player has one or more hills where ants will spawn. The objective is for players to seek and destroy the most enemy ant hills while defending their own hills. Players must also gather food to spawn more ants, however, if all of a player's hills are destroyed they can't spawn any more ants."

What Larry Page really needs to do to return Google to its startup roots - 0 views

  • I worked at Google from 2005-2010, and saw the company go through many changes, and a huge increase in staff.  Most importantly, I saw the company go from a place where engineers were seen as violent disruptors and innovators, to a place where doing things “The Google Way” was king, and where thinking outside the box was discouraged and even chastised.
  • Let engineers do what they do best, and forget the rest.
  • This is probably the most important single point.  Engineers at Google spend way too much time fussing about with everything other than engineering and product design.
  • ...2 more annotations...
  • Meetings.  Seriously, people are drenched in “status update” and “team” meetings.
  • Weekly Snippets, perf, etc. I was continually amazed by the amount of “extra cruft work” that goes on.  I know it sounds important, but engineers should be coding & designing.
    An opinion piece by an ex-Googler, talking, among other things, about how corporate culture is creeping into Google. I've highlighted some snippets which I've found eerily familiar :)

Can Google Predict the Stock Market? - ScienceNOW - 2 views

    Twitter Mood Predicts The Stock Market
    "An analysis of almost 10 million tweets from 2008 shows how they can be used to predict stock market movements up to 6 days in advance"

    not overly impressive:
    "The Google data could not predict the weekly fluctuations in stock prices. However, the team found a strong correlation between Internet searches for a company's name and its trade volume, the total number of times the stock changed hands over a given week."
    Likewise, I can predict the statistical properties of white noise :-)
    the problem is that usually the google search queries and the twitter updates happen after a crisis for example. I dont really think that people all over the world suddenly realised that Lehman would collapse and started googling it like crazy before it collapsed. More likely they did it afterwards.

    you propably already know,I post it for the twitter account and for your comments

    once again one of these initiatives that came up from a situation and that would never have been possible with a top-down approach .... fantastic!
    and as Dario said: we are apparently where NASA still has to go with this :-)
    Actually, NASA Ames did that already within the NASA Open Source Agreement in 2008 for a V&V software!
    indeed ... you are right .... interesting project btw - they started in 1999, were in 2005 the first NASA project on Sourceforge and won several awards ....
    then this entry why they did not participate last year:
    "05/01/09: Skipping this years Google Summer-of-Code - many of you have asked why we are not participating in this years Summer of Code. The answer is that both John and Peter were too busy with other assignments to set this up in time. We will be back in 2010. At least we were able to compensate with a limited number of NASA internships to continue some of last years projects."
    .... but I could not find them in this years selected list - any clue?
    but in any case, according to the apple guru, Java is a dying technology, so their project might as well ...
    They participate under the name "The Java Pathfinder Team" ( It is actually a very useful project for both education and industry (Airbus created a consortium on model checking soft, and there is a lot of research on it)
    As far as I know, TAS had some plans of using Java onboard spacecrafts, 2 years ago. Not sure the industry is really sensible about Jobs' opinions ;) particularly if there is no better alternative!
nikolas smyrlakis / Technology - Facebook becomes bigger hit than Google - 1 views

    In a sign that the web is becoming more sociable than searchable

    Although Facebook is enjoying rapid growth, it is only beginning to cash in on its success. Revenues at the social media company are estimated to be in the range of $1bn to $1.5bn this year, while Google took in $23.7bn last year.

    Ugh... no operator overloading, no efficient generic programming and no lambda expressions... Only time will tell, but I don't understand who the intended audience is: I think that Python guys won't care about the (supposedly) increased performance (and you can interface C/C++ with Python easily) and that C++ programmers (I mean, the hardcore serious C++ Boost-like programmers, no the Java-like whiners :P) won't have their beloved templates pried from their cold dead hands with ease.
    yeah though I think especially operator overloading is not going to be a main problem, it is as with the JS library though quite thinkable that lots of users will switch or use it (or being put to use it...) because it is done by Google
    Having Google backing it will certainly help, even though they are presenting it as a "system level" (i.e., hard-core) language, and in that domain it is much more difficult to bullshit your way to a position of relevance.

    Look at Java: Sun pushed it like hell and it is certainly widely used in many contexts (corporate, web and embedded markets mostly), yet it completely failed to win the hearts of "open-source" developers (or, more generally, of those developers who are not forced to use it by virtue of some management-driven decision).
    "or, more generally, of those developers who are not forced to use it by virtue of some management-driven decision" completely agree with that!!
