Software 'no more accurate than untrained humans' at judging reoffending risk | US news... - 0 views

  •  
    "The algorithm, called Compas (Correctional Offender Management Profiling for Alternative Sanctions), is used throughout the US to weigh up whether defendants awaiting trial or sentencing are at too much risk of reoffending to be released on bail.

    Since being developed in 1998, the tool is reported to have been used to assess more than one million defendants. But a new paper has cast doubt on whether the software's predictions are sufficiently accurate to justify its use in potentially life-changing decisions."

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."

Who do you trust? How data is helping us decide | Technology | The Guardian - 0 views

  •  
    "Should we embrace these new trust algorithms? Baveja and Shapiro acknowledge the responsibility that comes with trying to take ethical decisions and translate them into code. How much of our personal information do we want trawled through in this way? And how comfortable are we with letting an algorithm judge who is trustworthy?"

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."

Computer science students should learn to cheat, not be punished for it - 0 views

  •  
    "There's a certain irony that, in fields outside of computer science, plagiarism is a sign that you didn't understand the question. Within computer science, the opposite is true. Not only have you found an acceptable solution, you've understood it enough to use it within the parameters of your own project."

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.""

Creators of MP3 bring it to an end - 0 views

  •  
    "Two decades on, the institute has decided to terminate the licensing programme for some MP3-related patents which effectively halts industry support.

    Although users can still listen to their MP3 files, inventors of new technologies will probably not include the file format in their blueprints as they turn to more advanced alternatives."

Hey, Computer Scientists! Stop Hating on the Humanities | WIRED - 0 views

  •  
    "My personal coding projects have presented similarly thorny ethical questions. Should I write a computer program that will download the communications of thousands of teenagers suffering from eating disorders posted on an anorexia advice website? Write a program to post anonymous, suicidal messages on hundreds of college forums to see which colleges offer the most support? My answer to these questions, incidentally, was "no". But I considered it. And the glory and peril of computers is that they magnify the impact of your whims: an impulse becomes a program that can hurt thousands of people."

Google reduces JPEG file size by 35% | Ars Technica UK - 0 views

  •  
    "Google has developed and open-sourced a new JPEG algorithm that reduces file size by about 35 percent-or alternatively, image quality can be significantly improved while keeping file size constant. Importantly, and unlike some of its other efforts in image compression (WebP, WebM), Google's new JPEGs are completely compatible with existing browsers, devices, photo editing apps, and the JPEG standard."

    "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."
