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."

China does facial recognition for animals: George Orwell's nightmare or a farm revoluti... - 0 views

    "Having mastered facial recognition for humans to an alarmingly precise degree, even picking out wanted criminals from huge crowds, Chinese tech whizzes are turning their attention to furrier faces. "We've been using it for sheep, pigs and cows," said Zhao Jinshi, who studied at Cornell University and founded Beijing Unitrace Tech, a company developing software for the agriculture industry."

  •  
    "Our social media platforms are powered by a surveillance-based business model designed to mine, manipulate, and extract our human experiences at any cost, causing a breakdown of our information ecosystem and shared sense of truth worldwide. This extractive business model is not built for us but built to exploit us."

Can we escape from information overload? | 1843 - 0 views

  •  
    "Our brains tend to lean on the visual, heavily prioritising sight over the other four senses. Ever since we climbed on to two feet as a species, taking our noses farther from the aroma-rich savannah floor, we have been wired to be seeing creatures and for better or worse we usually experience the what's-next-what's-next of this world through our peepers."

    "These experiments in computational creativity are enabled by the dramatic advances in deep learning over the past decade. Deep learning has several key advantages for creative pursuits. For starters, it's extremely flexible, and it's relatively easy to train deep-learning systems (which we call models) to take on a wide variety of tasks."

How bad were Ofqual's grades - by Huy Duong - HEPI - 0 views

  •  
    "Therefore even Ofqual's best model significantly worsened grade accuracy for most A-level subjects when the cohort size is below 50, which is common (almost 62% of the total in 2019). For GCSEs, even with larger cohorts, the best model would have worsened the grade accuracy for Maths and Sciences. A very conservative figure of 25% of wrong grades would have amounted to 180,000 wrong A-level grades and 1.25 million wrong GCSE grades."

The Information Catastrophe: Digital Content on Track to Equal Half Earth's Mass by 2245 - 0 views

    "Eventually, we will reach a point of full saturation, a period in our evolution in which digital bits will outnumber atoms on Earth, a world "mostly computer simulated and dominated by digital bits and computer code," according to an article published in AIP Advances, by AIP Publishing."

North Dakota's COVID-19 contact tracing app leaks location data to Foursquare and a Goo... - 0 views

  •  
    "The app, called Care19, and produced by a company called ProudCrowd that also makes a location-based social networking app for North Dakota State sports fans, generates a random ID number for each person who uses it. Then, it can "anonymously cache the individual's locations throughout the day," storing information about where people spent at least 10 minutes at a time, according to the state website. If users test positive for the coronavirus, they can provide that information to the North Dakota Department of Health for contact-tracing purposes so that other people who spent time near virus patients can potentially be notified."

    "This time the model could look at both the surrounding words and the content of the image to fill in the blank. Through millions of repetitions, it could then discover not just the patterns among the words but also the relationships between the words and the elements in each image."

    "They then analysed how diverse the individuals' work was at different points in their careers. This was assessed using an artificial intelligence system that was trained, in the case of art, to "recognise" different styles by features such as the brush strokes, shapes and objects in a piece, while in the case of film, it was trained to classify a director's work based on plot and cast information. For science, the system identified different research topics based on the papers cited within a researcher's publications."

Modelers Project A Calming Of The Pandemic In The U.S. This Winter : Shots - Health New... - 0 views

  •  
    "or its latest update, which it released Wednesday, the COVID-19 Scenario Modeling Hub combined nine different mathematical models from different research groups to get an outlook for the pandemic for the next six months. "Any of us who have been following this closely, given what happened with delta, are going to be really cautious about too much optimism," says Justin Lessler at the University of North Carolina, who helps run the hub. "But I do think that the trajectory is towards improvement for most of the country," he says. The modelers developed four potential scenarios, taking into account whether or not childhood vaccinations take off and whether a more infectious new variant should emerge. "

The future of cybersecurity: Your body as a hacker-proof network | ZDNet - 1 views

  •  
    "The Purdue researchers have created Electro-Quasistatic Human Body Communication (EQS-HBC) which uses low-frequency, carrier-less broadband transmission, and so keeps the signal almost entirely within the human body. That means data from pacemakers and other implantable medical devices would only be readable a handful of centimetres outside the wearer."
  •  
    "Increasing numbers of implantable medical devices are now gaining internet connectivity, giving doctors the ability to monitor patients health remotely, and even update the devices to tweak a treatment plan. Unfortunately, that flexibility offers a way for hackers to hijack that hardware, and even potentially make changes to the way the devices work. While so far no attacks have been successful, proof-of-concept attacks have been available for years"

UK government 'hackathon' to search for ways to use AI to cut asylum backlog | Immigrat... - 0 views

  •  
    "The Home Office plans to use artificial intelligence to reduce the asylum backlog, and is launching a three-day hackathon in the search for quicker ways to process the 138,052 undecided asylum cases. The government is convening academics, tech experts, civil servants and business people to form 15 multidisciplinary teams tasked with brainstorming solutions to the backlog. Teams will be invited to compete to find the most innovative solutions, and will present their ideas to a panel of judges. The winners are expected to meet the prime minister, Rishi Sunak, in Downing Street for a prize-giving ceremony."

Sharing an article makes us feel more knowledgeable - even if we haven't read it - The ... - 0 views

  •  
    "One of the beautiful things about the internet is the sheer amount of knowledge it contains: if you're interested in any topic, you can find a surfeit of information about it in an instant. But this can also have a downside. Search engines can end perpetuating bias, for example. And research by Adrian Ward from the University of Texas, Austin suggests that we can mistake information we've searched for as our own knowledge. Now, in a new paper in the Journal of Consumer Psychology, Ward and colleagues have found that sharing information online also makes us feel that our knowledge has increased - even if we haven't read it."

How come GPT can seem so brilliant one minute and so breathtakingly dumb the next? - 0 views

  •  
    "In some sense, GPT is like a glorified version of cut and paste, where everything that is cut goes through a paraphrasing/synonymy process before it is paste but together-and a lot of important stuff is sometimes lost along the way. When GPT sounds plausible, it is because every paraphrased bit that it pastes together is grounded in something that actual humans said, and there is often some vague (but often irrelevant) relationship between.. At least for now, it still takes a human to know which plausible bits actually belong together."
