Facebook's spam filter blocked the most popular articles about its 50m user breach / Bo... - 0 views

  •  
    "The articles were so widely and quickly shared that they triggered Facebook's spam filters, which blocked the most popular stories about the breach, including an AP story and a Guardian story.

    There's no reason to think that Facebook intentionally suppressed embarrassing news about its own business. Rather, this is a cautionary tale about the consequences of content filtering on big platforms."

    Machine learning image classifiers use context clues to help understand the contents of a room, for example, if they manage to identify a dining-room table with a high degree of confidence, that can help resolve ambiguity about other objects nearby, identifying them as chairs.

    The downside of this powerful approach is that it means machine learning classifiers can be confounded by confusing, out-of-context elements in a scene, as is demonstrated in The Elephant in the Room, a paper from a trio of Toronto-based computer science academics."

Yuval Noah Harari on Why Technology Favors Tyranny - The Atlantic - 1 views

    "Can you guess how long AlphaZero spent learning chess from scratch, preparing for the match against Stockfish 8, and developing its genius instincts? Four hours. For centuries, chess was considered one of the crowning glories of human intelligence. AlphaZero went from utter ignorance to creative mastery in four hours, without the help of any human guide."

    "The groundbreaking artificial intelligence system, developed by the AI-outfit DeepMind with Moorfields eye hospital NHS foundation trust and University College London, was capable of correctly referring patients with more than 50 different eye diseases for further treatment with 94% accuracy, matching or beating world-leading eye specialists."

Magical thinking about machine learning won't bring the reality of AI any closer | John... - 0 views

  •  
    " Critics have pointed out that the old computing adage "garbage in, garbage out" also applies to ML. If the data from which a machine "learns" is biased, then the outputs will reflect those biases. And this could become generalised: we may have created a technology that - however good it is at recommending films you might like - may actually morph into a powerful amplifier of social, economic and cultural inequalities."

A.I. recreates periodic table of elements from scratch - Futurity - 0 views

  •  
    "A new artificial intelligence (AI) program recreated the periodic table of elements in just a few hours.

    It took nearly a century of trial and error for human scientists to organize the periodic table of elements, arguably one of the greatest scientific achievements in chemistry, into its current form."

Rise of the machines: has technology evolved beyond our control? | Books | The Guardian - 0 views

  •  
    "In October 2016, algorithms reacted to negative news headlines about Brexit negotiations by sending the pound down 6% against the dollar in under two minutes, before recovering almost immediately. Knowing which particular headline, or which particular algorithm, caused the crash is next to impossible. When one haywire algorithm started placing and cancelling orders that ate up 4% of all traffic in US stocks in October 2012, one commentator was moved to comment wryly that "the motive of the algorithm is still unclear"."

This AI Knows Who You Are by the Way You Walk - 0 views

    "Neural networks can find telltale patterns in a person's gait that can be used to recognize and identify them with almost perfect accuracy, according to new research published in IEEE Transactions on Pattern Analysis and Machine Intelligence. The new system, called SfootBD, is nearly 380 times more accurate than previous methods, and it doesn't require a person to go barefoot in order to work. It's less invasive than other behavioral biometric verification systems, such as retinal scanners or fingerprinting, but its passive nature could make it a bigger privacy concern, since it could be used covertly."

Chinese schools are testing AI that grades papers almost as well as teachers | VentureBeat - 0 views

  •  
    "It is also self-improving. The 10-year-old grading software leverages deep learning algorithms to "compare notes" with human teachers' scores, suggestions, and comments. An engineer involved in the project compared its capabilities to those of AlphaGo, the record-breaking AI Go player developed by Google subsidiary DeepMind."

Police trial AI software to help process mobile phone evidence | UK news | The Guardian - 0 views

  •  
    "Cellebrite, the Israeli-founded and now Japanese-owned company behind some of the software, claims a wider rollout would solve problems over failures to disclose crucial digital evidence that have led to the collapse of a series of rape trials and other prosecutions in the past year. However, the move by police has prompted concerns over privacy and the potential for software to introduce bias into processing of criminal evidence."

Here's How Scientists Are Using Machine Learning to Predict the Unpredictable - 0 views

    "More than just a poetic metaphor, the butterfly effect says that there are some things that even the most advanced science can never predict. Well, that list of things just got a lot shorter. Scientists from the University of Maryland have used machine learning to predict chaos."

How babies learn - and why robots can't compete | News | The Guardian - 0 views

    "He had discovered that human learning was communal and interactive. For a robot, the acquisition of language was abstract and formulaic. For us, it was embodied, emotive, subjective, quivering with life. The future of intelligence wouldn't be found in our machines, but in the development of our own minds."

Chinese chatbots are revolting against the Communist Party - 0 views

  •  
    "The chatbots - BabyQ and the Microsoft-created XiaoBing - were yanked from Chinese messaging app QQ, according to the Financial Times, after they started providing answers that weren't satisfactory to the glorious party. 

    According to FT, BabyQ would answer the question, "Do you love the Communist Party?" with "No." XiaoBing's transgressions were a bit more direct, declaring for some users "My China dream is to go to America" and answering other patriotic questions with "I'm having my period, wanna take a rest.""

Researchers shut down AI that invented its own language - 0 views

  •  
    " The observations made at Facebook are the latest in a long line of similar cases. In each instance, an AI being monitored by humans has diverged from its training in English to develop its own language. The resulting phrases appear to be nonsensical gibberish to humans but contain semantic meaning when interpreted by AI "agents." "

Curious AI learns by exploring game worlds and making mistakes | New Scientist - 0 views

  •  
    "This type of approach can speed up learning times and improve the efficiency of algorithms, says Max Jaderberg at Google's AI company DeepMind. The company used a similar technique last year to teach an AI to explore a virtual maze. Its algorithm learned much more quickly than conventional reinforcement learning approaches. "Our agent is far quicker and requires a lot less experience from the world to train, making it much more data efficient," he says."

    ""We'd have to show them 100,000 penny-farthings and tell them it's a bike," Giannandrea says. Then-looking on the bright side-he adds that "once they'd seen 100,000, they'd probably be better at identifying them than humans are.""

Basic common sense is key to building more intelligent machines | New Scientist - 0 views

  •  
    "At Imperial College London, Murray Shanahan and colleagues are working on a way around this problem using an old, unfashionable technique called symbolic AI. "Basically this meant an engineer labelled everything for the AI," says Shanahan. His idea is to combine this with modern machine learning.

    Symbolic AI never took off, because manually describing everything quickly proved overwhelming. Modern AI has overcome that problem by using neural networks, which learn their own representations of the world around them. "They decide what is salient," says Marta Garnelo, also at Imperial College."
