Algorithms Identify People with Suicidal Thoughts - IEEE Spectrum - 0 views

  •  
    "Brain scans, however, are quite telling, especially when analyzed with an algorithm, Brent and his colleagues discovered. "We're trying to figure out what's going on in somebody's brain when they're thinking about suicide," says Brent. 

    These scans, taken using fMRI, or functional magnetic resonance imaging, show that strong words such as 'death,' 'trouble,' 'carefree,' and 'praise,' trigger different patterns of brain activity in people who are suicidal, compared with people who are not. That means that people at risk of suicide think about those concepts differently than everyone else-evidenced by the levels and patterns of brain activity, or neural signatures."

    "This RFID-enabled device allowed its proud new owners to do things such as log into their computer, open doors and purchase food in the office cafeteria with a flick of the wrist. Nearly half of the company's 85 workers had the device implanted when the firm held a "chip party".

Real life CSI: Google's new AI system unscrambles pixelated faces | Technology | The Gu... - 0 views

  •  
    "Google's neural networks have achieved the dream of CSI viewers everywhere: the company has revealed a new AI system capable of "enhancing" an eight-pixel square image, increasing the resolution 16-fold and effectively restoring lost data.

    The neural network could be used to increase the resolution of blurred or pixelated faces, in a way previously thought impossible; a similar system was demonstrated for enhancing images of bedrooms, again creating a 32x32 pixel image from an 8x8 one."

    "Yet the balance of experimental evidence over the past thirty years suggests that this is not the case. Not only would removing anonymity fail to consistently improve online community behavior - forcing real names in online communities could also increase discrimination and worsen harassment."

    The insurer will examine posts and likes by the Facebook user, although not photos, looking for habits that research shows are linked to these traits. These include writing in short concrete sentences, using lists, and arranging to meet friends at a set time and place, rather than just "tonight"."

    ""The people who are on the list are not guilty until they've been prosecuted and taken to court, and the system makes that very clear", Simon says - and under the Data Protection Act "if anyone misuses that data there are very significant fines".

    Simon is also sanguine about the risk of misidentification. Images from the watch list will be sent with alerts so staff can check that there's a good match, he says. "

Penn News | Penn Study: Americans Give Up Personal Data for Discounts, They Believe Mar... - 0 views

  •  
    "The survey found that more than half of Americans say they do not want to lose control over their information but also believe this loss of control has already happened. Turow argues that marketers misrepresent Americans' behaviors by categorizing their acceptance of company discounts in exchange for personal data as rational acceptance of "tradeoffs."

The dick pic test: are you happy to show the government yours? | James Ball | Comment i... - 0 views

  •  
    "If you're doing nothing wrong, and have nothing to hide from your government, then mass surveillance holds no fears for you. This argument might be the oldest straw man in the privacy debate, but it's also a decent reflection of the state of the argument. In the UK's first major election since the Snowden revelations, privacy is a nonissue.

    This is a shame, because when it comes down to it, many of us who are doing nothing wrong have plenty we would prefer to hide."

Mass Wikipedia Edit To Make The Internet Less Sexist - 0 views

  •  
    ""This project also came on the heels of a very public debate about structural sexism in Wikipedia. [This] began when writer Amanda Filipacchi wrote a New York Times op-ed on a problematic editorial practice being implemented by a number of Wikipedia editors: women were being removed from the 'American Novelists' category and moved into a subcategory for 'American Women Novelists.'" Filipacchi's piece set the internet on fire, sparking a mass call for reform."

Why your Facebook friends could scupper a student loan | Education | The Guardian - 0 views

  •  
    "Graduated top of your class in Ghana and managed to land a place on an MBA at Oxford? Then you're heading for a salary high enough to make repaying your student loan a cinch - especially if half your Facebook followers are from McKinsey. At least, this is the kind of calculation being made by private funders stepping into the increasingly complex and competitive student loans market."

    "Teatreneu's administrators found an ingenious solution: partnering with the advertising agency Cyranos McCann, they fitted the back of every seat with fancy tablets that can analyse facial expressions. Under the new model, visitors enter the club for free but have to pay 30 cents for every laugh recognised by the tablet - with a cap of €24 (or 80 laughs) per show. A mobile app makes it easier to complete the payment; the overall ticket prices have reportedly gone up by €6. As a bonus, you can also share your smiling selfie with friends: the path from funny to viral has never been shorter."

    "Now, the number of combinations of these columns grows exponentially with the number of columns. So if you have many, many columns-and we do in modern databases-you'll get up into millions and millions of attributes for each person.

    Now, if I start allowing myself to look at all of the combinations of these features-if you live in Beijing, and you ride bike to work, and you work in a certain job, and are a certain age-what's the probability you will have a certain disease or you will like my advertisement? Now I'm getting combinations of millions of attributes, and the number of such combinations is exponential; it gets to be the size of the number of atoms in the universe."
