Who Is Working to End the Threat of AI-Generated Deepfakes - 0 views

  • ata poisoning techniques to essentially disturb pixels within an image to create invisible noise, effectively making AI art generators incapable of generating realistic deepfakes based on the photos they’re fed.
  • Higher resolution images work even better, he said, since they include more pixels that can be minutely disturbed.
  • Google is creating its own AI image generator called Imagen, though few people have been able to put their system through its paces. The company is also working on a generative AI video system.
  • ...4 more annotations...
  • Salman said he could imagine a future where companies, even the ones who generate the AI models, could certify that uploaded images are immunized against AI models. Of course, that isn’t much good news for the millions of images already uploaded to the open source library like LAION, but it could potentially make a difference for any image uploaded in the future.
  • there are some AI systems that can detect deepfake videos, and there are ways to train people to detect the small inconsistencies that show a video is being faked. The question is: will there come a time when neither human nor machine can discern if a photo or video has been manipulated?
  • Back in September, OpenAI announced users could once again upload human faces to their system, but claimed they had built in ways to stop users from showing faces in violent or sexual contexts. It also asked users not to upload images of people without their consent
  • Noah asked Murati if there was a way to make sure AI programs don’t lead us to a world “where nothing is real, and everything that’s real, isn’t?”

The top 10 emerging technologies of 2016 - 1 views

  •  
    The World Economic Forum's annual list of this year's breakthrough technologies, published today, includes "socially aware" open AI. As technology for AI assistants expands, imagine that you could walk up to a display in a museum and ask a custom AI assistant any question you like about what you are seeing. Siri and Cortana and Google Assistant and Amazon Echo try to answer questions on all topics, but what if museums and other organizations could build their own add-on packs for their sphere of knowledge? The Getty, for example, would prepare answers to every question they've ever heard about "Statue of a Victorious Youth" and museum visitors (or maybe anybody in the world) could use the add-on pack to find out what they want to know.

Are we witnessing the dawn of post-theory science? | Artificial intelligence (AI) | The... - 0 views

  • we’ve realised that artificial intelligences (AIs), particularly a form of machine learning called neural networks, which learn from data without having to be fed explicit instructions, are themselves fallible.
  • The second is that humans turn out to be deeply uncomfortable with theory-free science.
  • there may still be plenty of theory of the traditional kind – that is, graspable by humans – that usefully explains much but has yet to be uncovered.
  • ...4 more annotations...
  • The theories that make sense when you have huge amounts of data look quite different from those that make sense when you have small amounts
  • The bigger the dataset, the more inconsistencies the AI learns. The end result is not a theory in the traditional sense of a precise claim about how people make decisions, but a set of claims that is subject to certain constraints.
  • theory-free predictive engines embodied by Facebook or AlphaFold.
  • “Explainable AI”, which addresses how to bridge the interpretability gap, has become a hot topic. But that gap is only set to widen and we might instead be faced with a trade-off: how much predictability are we willing to give up for interpretability?

Will Future Technology Create More Jobs Than It Replaces? - 0 views

  •  
    "Whether AI does or does not become the nightmare of some science fiction, we are certain it will have fundamental impacts on the nature of work, worldwide. And the world needs to think seriously about this now, because it may take a generation or more to make serious changes necessary to improve our work-technology future prospects," says Jerome Glenn, CEO of The Millennium Project.

What the research says about 4-day school weeks - MindShift - 0 views

  • (City students were excluded from the analysis because no city schools had adopted four-day weeks. Only rural, small town and suburban students were included.)
  • The switch seemed to hurt reading achievement more than math achievement.
  • Rural schools accounted for seven out of 10 schools on the four-day schedule in this study.
  • ...8 more annotations...
  • Rural four-day students generally learned as much as rural five-day day students. Statistically, both groups’ test scores rose by about the same amount every year.
  • small town and suburban students who switched to four-day weeks were far worse off than other students in the state
  • One possible explanation, Morton says, is sports. Many rural athletes and young student fans leave school early on Fridays or skip school altogether because of the great distances to travel to away games. In effect, many five-day students are only getting four-days of instruction in rural America.
  • The four-day work week is an attractive work perk in rural America that may lure better teachers.
  • By this theory, four-day schools may make it easier to hire better teachers, who could accomplish in four days what a less skilled teacher accomplishes in five days.
  • five-day weeks have their own drawbacks in rural America: hidden absences, skipped lessons and lower quality teachers.
  • Hispanic students, who accounted for one out of every six rural students in this study, suffered much more from four-day weeks than white students did. (Native American students, who made up one of every 10 rural students, did relatively better with the four-day week.)
  • biggest surprise to me in this review of the research is how tiny the cost savings are: 1 to 2 percent.  It does save some money not to run the heat or buses one day a week, but the largest expenses, teacher salaries, stay the same.
