Fastly says single customer triggered bug behind mass internet outage | Internet | The ... - 0 views

  •  
    "An internet blackout that knocked out some of the world's biggest websites on Tuesday was ultimately caused by a single customer updating their settings, the infrastructure provider Fastly has revealed. A bug in Fastly's code introduced in mid-May had lain dormant until Tuesday morning, according to Nick Rockwell, the company's head of engineering and infrastructure. When the unnamed customer updated their settings, it triggered the flaw, which ultimately took down 85% of the company's network."

Amid a Pandemic, a Health Care Algorithm Shows Promise and Peril - 0 views

  •  
    "But historically, these tools have been put into use only after a rigorous peer review of the raw data and statistical analyses used to develop them. Epic's Deterioration Index, on the other hand, remains proprietary despite its widespread deployment. Although physicians are provided with a list of the variables used to calculate the index and a rough estimate of each variable's impact on the score, we aren't allowed under the hood to evaluate the raw data and calculations.

This Researcher Says AI Is Neither Artificial nor Intelligent | WIRED - 0 views

  •  
    "We need to look at the nose to tail production of artificial intelligence. The seeds of the data problem were planted in the 1980s, when it became common to use data sets without close knowledge of what was inside, or concern for privacy. It was just "raw" material, reused across thousands of projects."

yes, all models are wrong - 0 views

  •  
    "According to Derek & Laura Cabrera, "wicked problems result from the mismatch between how real-world systems work and how we think they work". With systems thinking, there is constant testing and feedback between the real world, in all its complexity, and our mental model of it. This openness to test and look for feedback led Dr. Fisman to change his mind on the airborne spread of the coronavirus."

'Typographic attack': pen and paper fool AI into thinking apple is an iPod | Technology... - 0 views

  •  
    "But even cleverest AI can be fooled with the simplest of hacks. If you write out the word "iPod" on a sticky label and paste it over the apple, Clip does something odd: it decides, with near certainty, that it is looking at a mid-00s piece of consumer electronics. In another test, pasting dollar signs over a picture of a dog caused it to be recognised as a piggy bank."

Gun Detection AI is Being Trained With Homemade 'Active Shooter' Videos - 0 views

  •  
    "The point of creating this vast portfolio of digital gun art is to feed an algorithm made to detect a firearm as soon as a security camera catches it being drawn by synthetically creating tens of thousands of ways each gun may appear. Arcarithm is one of several companies developing automated active shooter detection technology in the hopes of selling it to schools, hotels, entertainment venues and the owners of any location that could be the site of one of America's 15,000 annual gun murders and 29,000 gun injuries."

New Facial Recognition Tech Only Needs Your Eyes and Eyebrows | by Dave Gershgorn | One... - 0 views

  •  
    "This week, the company released a new form of facial recognition called periocular recognition, which can supposedly identify individuals by just their eyes and eyebrows. Rank One says the new system uses an entirely different algorithm from its standard facial recognition system and is specifically meant for masked individuals. Rank One says it will ship the technology to all of its active customers for free."

    "But while CSV files can be any size, Microsoft Excel files can only be 1,048,576 rows long - or, in older versions which PHE may have still been using, a mere 65,536. When a CSV file longer than that is opened, the bottom rows get cut off and are no longer displayed. That means that, once the lab had performed more than a million tests, it was only a matter of time before its reports failed to be read by PHE."

    "That can include statistical or machine learning algorithms that rely on police records detailing the time, location, and nature of past crimes in a bid to predict if, when, where, and who may commit future infractions. In theory, this should help authorities use resources more wisely and spend more time policing certain neighborhoods that they think will yield higher crime rates."

    "But, as he and other modellers warn, much information about how SARS-CoV-2 spreads is still unknown and must be estimated or assumed - and that limits the precision of forecasts. An earlier version of the Imperial model, for instance, estimated that SARS-CoV-2 would be about as severe as influenza in necessitating the hospitalization of those infected. That turned out to be incorrect."
