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."

"The Biology of Disinformation," a paper by Rushkoff, Pescovitz, and Dunagan / Boing Boing - 0 views

  •  
    "Already, artificially intelligent software can evolve false political and social constructs highly targeted to sway specific audiences. Users find themselves in highly individualized, algorithmically determined news and information feeds, intentionally designed to: isolate them from conflicting evidence or opinions, create self-reinforcing feedback loops of confirmation, and untether them from fact-based reality. And these are just early days. If memes and disinformation have been weaponized on social media, it is still in the musket stage."

Facebook Is Now Using AI to Help Prevent Suicides - 0 views

  •  
    "Facebook has detailed the steps it's taking to get help for people who need it. Which involves using artificial intelligence to "detect posts or live videos where someone might be expressing thoughts of suicide," identifying appropriate first responders, and then employing more people to "review reports of suicide or self harm".

    The social network has been testing this system in the U.S. for the last month, and "worked with first responders on over 100 wellness checks based on reports we received via our proactive detection efforts." In some cases the local authorities were notified in order to help."

Computer says no: why making AIs fair, accountable and transparent is crucial | Science... - 0 views

  •  
    "In October, American teachers prevailed in a lawsuit with their school district over a computer program that assessed their performance.

    The system rated teachers in Houston by comparing their students' test scores against state averages. Those with high ratings won praise and even bonuses. Those who fared poorly faced the sack.

    The program did not please everyone. Some teachers felt that the system marked them down without good reason. But they had no way of checking if the program was fair or faulty: the company that built the software, the SAS Institute, regards its algorithm a trade secret and would not disclose its workings."

The Age of the Algorithm - 99% Invisible - 0 views

  •  
    "But the answer to how he was chosen is actually an algorithm, a computer program that crunched through reams of data, looking at how much each passenger had paid for their ticket, what time they checked in, how often they flew on United, and whether they were part of a rewards program. The algorithm likely determined that Dr. Dao was one of the least valuable customers on the flight at the time."

Meet Dr. A.I.: Can an App Diagnose Your Health Issues? - 0 views

  •  
    "The results may seem similar to what you'd get if you'd searched WebMD, Mayo Clinic, etc. The difference is that Dr. A.I. pulls in many more data points than those sites do, then combines artificial intelligence with a massive database to pinpoint the most likely results in your specific case. It doesn't just find all possible ailments and list them for you to explore further on your own."

Scientists discover how the brain recognises faces - by reading monkey's minds | Scienc... - 0 views

  •  
    "Instead, the new work shows our brains rely on the kind of maths that an algorithm might use to perform the task. In fact, Tsao and her colleague, Steven Le Chang, stumbled on their discovery while working on computer vision. The pair had initially set themselves the challenge of coming up with a way of reliably converting facial images into a numerical representation."

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."

The coded gaze: biased and understudied facial recognition technology / Boing Boing - 0 views

  •  
    " "Why isn't my face being detected? We have to look at how we give machines sight," she said in a TED Talk late last year. "Computer vision uses machine-learning techniques to do facial recognition. You create a training set with examples of faces. However, if the training sets aren't really that diverse, any face that deviates too much from the established norm will be harder to detect.""

    "Automated decision-making is appealing to businesses as it can save time and eliminate human emotional volatility.

    "People have a bad day and it then colors their perception of the world and they make different decisions. In a hedge fund that's a big deal," he added."

Top 10 AI failures of 2016 - TechRepublic - 0 views

  •  
    "But with all of the successes of AI, it's also important to pay attention to when, and how, it can go wrong, in order to prevent future errors. A recent paper by Roman Yampolskiy, director of the Cybersecurity Lab at the University of Louisville, outlines a history of AI failures which are "directly related to the mistakes produced by the intelligence such systems are designed to exhibit." According to Yampolskiy, these types of failures can be attributed to mistakes during the learning phase or mistakes in the performance phase of the AI system."

Lip-Reading AI Smashes Humans At Interpreting Silent Sentences | Digital Trends - 0 views

  •  
    "The performance of LipNet compares incredibly favorably to human lipreading experts on GRID corpus, the largest publicly-available sentence-level lipreading dataset. In fact, where human experts got just 52 percent, LipNet scored 93 percent. Its sentence-based approach to lip-reading also smashed the best previous attempt by a machine, which managed 79.6 percent accuracy on the same dataset."

School for teenage codebreakers to open in Bletchley Park | Technology | The Guardian - 0 views

  •  
    "The school will teach cyber skills to some of the UK's most gifted 16- to 19-year-olds. It will select on talent alone, looking in particular for exceptional problem solvers and logic fiends, regardless of wealth or family background, according to Alastair MacWillson, a driving force behind the initiative.

    "The cyber threat is the real threat facing the UK, and the problem it's causing the UK government and companies is growing exponentially," said MacWillson, chair of Qufaro, a not-for-profit organisation created by a consortium of cybersecurity experts for the purposes of education."

    "Given the complexity of the law, and the preference for simplicity when it comes to AI programming, it's an ambitious project. "We'd like to expand to other areas of civil law, and we're already in touch with German universities," Bull says. "But we're not out to make a program that provides a too-complex analysis. We really want to keep it as a starting point for victims.""

Stealing an AI algorithm and its underlying data is a "high-school level exercise" - Qu... - 0 views

  •  
    "Researchers have shown that given access to only an API, a way to remotely use software without having it on your computer, it's possible to reverse-engineer machine learning algorithms with up to 99% accuracy. In the real world, this would mean being able to steal AI products from companies like Microsoft and IBM, and use them for free. Small companies built around a single machine learning API could lose any competitive advantage."
