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.

    "But today that universe seeks and surrounds you. When you first join Facebook you make a few choices of your own. But soon the algorithm starts narrowing your options and deciding what further choices to present to you. Because many of us rely on a limited number of news sources that populate our social media feeds, our information universe becomes more and more niche. For Trump supporters, that universe is often paramilitary."

Google's 'experiment' hiding Australian news just shows its inordinate power | Belinda ... - 0 views

  •  
    "In the midst of a global pandemic and an unprecedented misinformation glut, Google has decided to hide some Australian news sites from its search results. It is "experimenting" with the lone supply of fact-checked, accountable information Australians can access right now."

Algorithms like YouTube's content ID harm fair use, free speech, and creativity | Boing... - 0 views

  •  
    "Because YouTube is the dominant player in the online video market, its choices dictate the norms of the whole industry. And unfortunately for independent creators, YouTube has proven to be more interested in appeasing large copyright holders than protecting free speech or promoting creativity. Through its automatic copyright filter, Content ID, YouTube has effectively replaced legal fair use of copyrighted material with its own rules."

Columbia researchers find white men are the worst at reducing AI bias | VentureBeat - 0 views

  •  
    "Researchers at Columbia University sought to shed light on the problem by tasking 400 AI engineers with creating algorithms that made over 8.2 million predictions about 20,000 people. In a study accepted by the NeurIPS 2020 machine learning conference, the researchers conclude that biased predictions are mostly caused by imbalanced data but that the demographics of engineers also play a role."

    "The paper, co-authored by researchers inside and outside Google, contended that technology companies could do more to ensure AI systems aimed at mimicking human writing and speech do not exacerbate historical gender biases and use of offensive language, according to a draft copy seen by Reuters."

As Algorithms Take Over More of the Economy, We Should Cede Control (Very) Carefully - 0 views

  •  
    "After being set an overarching goal like maximizing profit, they develop their own strategies based on experience of the market, often with little human oversight. The most advanced also use forms of AI whose workings are opaque even if humans wanted to peer inside."

DeepMind AI cracks 50-year-old problem of protein folding | DeepMind | The Guardian - 0 views

  •  
    ""It marks an exciting moment for the field," said Demis Hassabis, DeepMind's founder and chief executive. "These algorithms are now becoming mature enough and powerful enough to be applicable to really challenging scientific problems." Advertisement Venki Ramakrishnan, the president of the Royal Society, called the work "a stunning advance" that had occurred "decades before many people in the field would have predicted"."

Facebook Manipulated the News You See to Appease Republicans, Insiders Say - Mother Jones - 0 views

  •  
    "What wasn't publicly known until now is that Facebook actually ran experiments to see how the changes would affect publishers-and when it found that some of them would have a dramatic impact on the reach of right-wing "junk sites," as a former employee with knowledge of the conversations puts it, the engineers were sent back to lessen those impacts. As the Wall Street Journal reported on Friday, they came back in January 2018 with a second iteration that dialed up the harm to progressive-leaning news organizations instead."

U.K. Found 'Critical' Weakness in Huawei Equipment - Bloomberg - 0 views

  •  
    ""Critical, user-facing vulnerabilities" were found in the Chinese supplier's fixed-broadband products caused by poor code quality and an old operating system, the Huawei Cyber Security Evaluation Centre Oversight Board said in a report. "U.K. operators needed to take extraordinary action to mitigate the risk.""

Doctors use algorithms that aren't designed to treat all patients equally - 0 views

  •  
    "The battle over algorithms in healthcare has come into full view since last fall. The debate only intensified in the wake of the coronavirus pandemic, which has disproportionately devastated Black and Latino communities. In October, Science published a study that found one hospital unintentionally directed more white patients than Black patients to a high-risk care management program because it used an algorithm to predict the patients' future healthcare costs as a key indicator of personal health. Optum, the company that sells the software product, told Mashable that the hospital used the tool incorrectly. "

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."

Twitter apologises for 'racist' image-cropping algorithm | Twitter | The Guardian - 0 views

  •  
    "But users began to spot flaws in the feature over the weekend. The first to highlight the issue was PhD student Colin Madland, who discovered the issue while highlighting a different racial bias in the video-conference software Zoom. When Madland, who is white, posted an image of himself and a black colleague who had been erased from a Zoom call after its algorithm failed to recognise his face, Twitter automatically cropped the image to only show Madland."

    "And that was a genuine first - the only time I can recall when an algorithmic decision had been challenged in public protests that were powerful enough to prompt a government climbdown. In a world increasingly - and invisibly - regulated by computer code, this uprising might look like a promising precedent."

YouTube's Plot to Silence Conspiracy Theories | WIRED - 0 views

    "Crucial to his success, he says, was YouTube's recommendation system, the feature that promotes videos for you to watch on the homepage or in the "Up Next" column to the right of whatever you're watching. "We were recommended constantly," he tells me. YouTube's algorithms, he says, figured out that "people getting into flat earth apparently go down this rabbit hole, and so we're just gonna keep recommending.""

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 lessons we all must learn from the A-levels algorithm debacle | WIRED UK - 0 views

  •  
    "More algorithmic decision making and decision augmenting systems will be used in the coming years. Unlike the approach taken for A-levels, future systems may include opaque AI-led decision making. Despite such risks there remain no clear picture of how public sector bodies - government, local councils, police forces and more - are using algorithmic systems for decision making."

Algorithm finds hidden connections between paintings at the Met | MIT CSAIL - 0 views

  •  
    "What Hamilton and his colleagues found surprising was that this approach could also be applied to helping find problems with existing deep networks, related to the surge of "deepfakes" that have recently cropped up. They applied this data structure to find areas where probabilistic models, such as the generative adversarial networks (GANs) that are often used to create deepfakes, break down. They coined these problematic areas "blind spots," and note that they give us insight into how GANs can be biased. Such blind spots further show that GANs struggle to represent particular areas of a dataset, even if most of their fakes can fool a human. "

  •  
    "Creating an algorithm that discriminates or shows bias isn't as hard as it might seem, however. As a first-year graduate student, my advisor asked me to create a machine-learning algorithm to analyze a survey sent to United States physics instructors about teaching computer programming in their courses."
