YouTube will temporarily increase automated content moderation | Engadget - 0 views

  •  
    "YouTube will rely more on machine learning and less on human reviewers during the coronavirus outbreak. Normally, algorithms detect potentially harmful content and send it to human reviewers for assessment. But these are not normal times, and in an effort to reduce the need for employees and contractors to come into an office, YouTube will allow its automated system to remove some content without human review."

Zoom's Flawed Encryption Linked to China - 0 views

  •  
    "MEETINGS ON ZOOM, the increasingly popular video conferencing service, are encrypted using an algorithm with serious, well-known weaknesses, and sometimes using keys issued by servers in China, even when meeting participants are all in North America, according to researchers at the University of Toronto."

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."

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."

Algorithms outdo us. But we still prefer human fallibility | Rafael Behr | Opinion | Th... - 0 views

    "Luddism refuses to die because each innovation creates a pool of people who feel economically or culturally dispossessed. The greater the leap forward, the wider the chasm of obsolescence. And the scale of the digital revolution defies hyperbole. No area of human activity is undisrupted. "

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."

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.

Facebook is bombarding rightwing users with ads for combat gear. See for yourself | Fac... - 0 views

  •  
    "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."

Digital dystopia: how algorithms punish the poor | Technology | The Guardian - 0 views

  •  
    "Vast sums are being spent by governments across the industrialized and developing worlds on automating poverty and in the process, turning the needs of vulnerable citizens into numbers, replacing the judgment of human caseworkers with the cold, bloodless decision-making of machines. "

    ""This is the first time such machine learning tools have been used in this context," says Fluri, "and we found that the deep artificial neural network enables us to extract more information from the data than previous approaches. We believe that this usage of machine learning in cosmology will have many future applications.""

Read Sacha Baron Cohen's scathing attack on Facebook in full: 'greatest propaganda mach... - 0 views

  •  
    "The greatest propaganda machine in history. Think about it. Facebook, YouTube and Google, Twitter and others - they reach billions of people. The algorithms these platforms depend on deliberately amplify the type of content that keeps users engaged - stories that appeal to our baser instincts and that trigger outrage and fear. It's why YouTube recommended videos by the conspiracist Alex Jones billions of times. It's why fake news outperforms real news, because studies show that lies spread faster than truth. And it's no surprise that the greatest propaganda machine in history has spread the oldest conspiracy theory in history - the lie that Jews are somehow dangerous. As one headline put it, "Just Think What Goebbels Could Have Done with Facebook.""

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."

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. "

Algorithms associating appearance and criminality have a dark past | Aeon Ideas - 0 views

  •  
    "However, the recent study's seemingly high-tech attempt to pick out facial features associated with criminality borrows directly from the 'photographic composite method' developed by the Victorian jack-of-all-trades Francis Galton - which involved overlaying the faces of multiple people in a certain category to find the features indicative of qualities like health, disease, beauty and criminality."

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"."

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."

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."
