A.I. can now create fake videos of people from a single picture

Researchers advance machine learning to create videos of people from single stills and paintings.

  • Samsung researchers improve AI modeling to quickly create realistic (but fake) videos.
  • The model uses "single-shot learning" to create videos from a single picture.
  • The application of the tech could be in telepresence, video conferencing and gaming.

An AI can now take a single picture of a person's face and animate it convincingly. This can lead to animating paintings and photos but also add to the mistrust of images and deepfakes online.

The new method from researchers at the Samsung AI Center in Moscow incorporates facial landmarks from a source face into the facial data from the target face to animate it. The target face will do anything done by the source face, which can be any talking head.

What is different here from previous technology that has been developed to achieve this is the fact that rather than needing a lot of data (like video) to analyze, this approach called "single-shot learning" needs just one image of a person's face. The video that is generated from that can show the face making a range of expressions and speaking with reasonable credibility.

The new tech front loads the process of facial landmark recognition with a large amount of data from a bank of talking head videos. It then trains the model to be very efficient in connecting parts of the target face with the source.

The new AI also uses the Generative Adversarial Network, having two models compete against each other in creating a more "real" result.

Here’s how adversarial learning works:

Where can you use this technology, other than contributing to the epidemic of fake news that is sure to eventually affect personal relationships as much as the national conversations? "Such ability has practical applications for telepresence, including videoconferencing and multi-player games, as well as [the] special effects industry," Samsung said.

Step inside the unlikely friendship of a former ACLU president and an ultra-conservative Supreme Court Justice.

Sponsored by Charles Koch Foundation
  • Former president of the ACLU Nadine Strossen and Supreme Court Justice Antonin Scalia were unlikely friends. They debated each other at events all over the world, and because of that developed a deep and rewarding friendship – despite their immense differences.
  • Scalia, a famous conservative, was invited to circles that were not his "home territory", such as the ACLU, to debate his views. Here, Strossen expresses her gratitude and respect for his commitment to the exchange of ideas.
  • "It's really sad that people seem to think that if you disagree with somebody on some issues you can't be mutually respectful, you can't enjoy each other's company, you can't learn from each other and grow in yourself," says Strossen.
  • The opinions expressed in this video do not necessarily reflect the views of the Charles Koch Foundation, which encourages the expression of diverse viewpoints within a culture of civil discourse and mutual respect.

3 ways to find a meaningful job, or find purpose in the job you already have

Learn how to redesign your job for maximum reward.

Videos
  • Broaching the question "What is my purpose?" is daunting – it's a grandiose idea, but research can make it a little more approachable if work is where you find your meaning. It turns out you can redesign your job to have maximum purpose.
  • There are 3 ways people find meaning at work, what Aaron Hurst calls the three elevations of impact. About a third of the population finds meaning at an individual level, from seeing the direct impact of their work on other people. Another third of people find their purpose at an organizational level. And the last third of people find meaning at a social level.
  • "What's interesting about these three elevations of impact is they enable us to find meaning in any job if we approach it the right way. And it shows how accessible purpose can be when we take responsibility for it in our work," says Hurst.

Physicist advances a radical theory of gravity

Erik Verlinde has been compared to Einstein for completely rethinking the nature of gravity.

Surprising Science
  • The Dutch physicist Erik Verlinde's hypothesis describes gravity as an "emergent" force not fundamental.
  • The scientist thinks his ideas describe the universe better than existing models, without resorting to "dark matter".
  • While some question his previous papers, Verlinde is reworking his ideas as a full-fledged theory.

UPS has been discreetly using self-driving trucks to deliver cargo

TuSimple, an autonomous trucking company, has also engaged in test programs with the United States Postal Service and Amazon.

Technology & Innovation
  • This week, UPS announced that it's working with autonomous trucking startup TuSimple on a pilot project to deliver cargo in Arizona using self-driving trucks.
  • UPS has also acquired a minority stake in TuSimple.
  • TuSimple hopes its trucks will be fully autonomous — without a human driver — by late 2020, though regulatory questions remain.
