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."

New brain-computer interface writes up to 90 characters per minute with your thoughts |... - 0 views

  •  
    "With this BCI, our study participant, whose hand was paralysed from spinal cord injury, achieved typing speeds of 90 characters per minute with 94.1% raw accuracy online, and greater than 99% accuracy offline with a general-purpose autocorrect."

NIST study finds facial recognition algorithms struggle to identify masked faces | Priv... - 0 views

  •  
    "A preliminary study finds that facial recognition algorithms struggle to identify people wearing masks. The study tested 89 commercial facial recognition algorithms, and the best had error rates between 5% and 50% in matching unmasked photos with photos of the same person wearing a digitally-applied mask. Masks both lowered the algorithms' accuracy rates and raised the number of failures to process. The more of the nose is covered by the mask the lower the algorithm's accuracy; however, error rates were generally lower with round masks; and the algorithms generally performed worse with black masks than with surgical blue ones. False positive remained stable or declined a small amount."

A Brain Scanner Combined with an AI Language Model Can Provide a Glimpse into Your Thou... - 0 views

  •  
    "Now researchers have taken a step forward by combining fMRI's ability to monitor neural activity with the predictive power of artificial intelligence language models. The hybrid technology has resulted in a decoder that can reproduce, with a surprising level of accuracy, the stories that a person listened to or imagined telling in the scanner. The decoder could even guess the story behind a short film that someone watched in the scanner, though with less accuracy."

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."

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."

MIT's 'Kinect of the Future' Device Tracks People Through Walls [VIDEO] - 0 views

  •  
    "The device tracks a single person with an accuracy of plus or minus 10 centimeters - about the size of an adult hand. Apart from the ability to "see" through a wall, its main advantage is that the person being tracked isn't required to wear a transmitter. While other location systems depend on Wi-Fi, this device can track a person's movements within the radius of its radio waves."

Artificial intelligence tool 'as good as experts' at detecting eye problems | Technolog... - 0 views

  •  
    "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."

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."

    "But its "surprising accuracy" was "very concerning". Questioned about this, he said that a database using facial recognition technology was unlikely to be a service that the company would create, but went on to say that "some company … is going to cross that line"."

JetBlue is the latest to use facial recognition technology in airports - 0 views

  •  
    "However, there is some concern about how accurate these new procedures will be. Apparently the facial recognition technology doesn't recognize all people will the same accuracy. White women and black people aren't as easily recognized as white men, meaning there could be some mismatching of identities. Some are also concerned that this is crossing the line in terms of passenger privacy."

The Citizen crime app hasn't made me safer - just more scared | Emma Brockes | Opinion ... - 0 views

  •  
    "Citizen, which was launched in 2017, is a glorified police scanner that promises to help users "stay safe and informed". It invites input from witnesses - mostly involving shaky phone footage of police milling around while a stretcher is carted by in the background - and, bafflingly, includes a comments section, in which users speculate fatuously on the crime in question and quibble over the accuracy of the map function. It is grimly fascinating, mildly addictive and, relative to its stated aims, totally without value."

In facial recognition challenge, top-ranking algorithms show bias against Black women |... - 0 views

  •  
    "The results are unfortunately not surprising - countless studies have shown that facial recognition is susceptible to bias. A paper last fall by University of Colorado, Boulder researchers demonstrated that AI from Amazon, Clarifai, Microsoft, and others maintained accuracy rates above 95% for cisgender men and women but misidentified trans men as women 38% of the time."

Police built an AI to predict violent crime. It was seriously flawed | WIRED UK - 1 views

  •  
    "A flagship artificial intelligence system designed to predict gun and knife violence before it happens had serious flaws that made it unusable, police have admitted. The error led to large drops in accuracy and the system was ultimately rejected by all of the experts reviewing it for ethical problems."

Don't Expect ChatGPT to Help You Land Your Next Job - 0 views

  •  
    "Shapiro said that using ChatGPT can be "great" in helping applicants "brainstorm verbs" and reframe language that can "bring a level of polish to their applications." At the same time, she said that submitting AI-generated materials along with job applications can backfire if applicants don't review them for accuracy. Shapiro said Jasper recruiters have interviewed candidates and discovered skills on their résumés that applicants said shouldn't be there or characterizations they weren't familiar with. Checking the AI-generated materials to ensure they accurately reflect an applicant's capabilities, she said, is critical if they're using ChatGPT - especially if the applicant gets hired."
