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.

To create wiser adults, add empathy to the school curriculum.
- Stories are at the heart of learning, writes Cleary Vaughan-Lee, Executive Director for the Global Oneness Project. They have always challenged us to think beyond ourselves, expanding our experience and revealing deep truths.
- Vaughan-Lee explains 6 ways that storytelling can foster empathy and deliver powerful learning experiences.
- Global Oneness Project is a free library of stories—containing short documentaries, photo essays, and essays—that each contain a companion lesson plan and learning activities for students so they can expand their experience of the world.
An extinction events expert sounds a dire warning.
- The supervolcano in Yellowstone National Park could cause an "ultra-catastrophe," warns an extinction events writer.
- The full eruption of the volcano last happened 640,000 years ago.
- The blast could kill billions and make United States uninhabitable.
Just before I turned 60, I discovered that sharing my story by drawing could be an effective way to both alleviate my symptoms and combat that stigma.
I've lived much of my life with anxiety and depression, including the negative feelings – shame and self-doubt – that seduced me into believing the stigma around mental illness: that people knew I wasn't good enough; that they would avoid me because I was different or unstable; and that I had to find a way to make them like me.
A joint study by two England universities explores the link between sex and cognitive function with some surprising differences in male and female outcomes in old age.
- A joint study by the universities of Coventry and Oxford in England has linked sexual activity with higher cognitive abilities in older age.
- The results of this study suggest there are significant associations between sexual activity and number sequencing/word recall in men. In women, however, there was a significant association between sexual activity in word recall alone - number sequencing was not impacted.
- The differences in testosterone (the male sex hormone) and oxytocin (a predominantly female hormone) may factor into why the male cognitive level changes much more during sexual activity in older age.
