Virtual assistants and robots are becoming increasingly sophisticated, interactive and human-like. To fully replicate human communication, however, artificial intelligence (AI) agents should not only be able to determine what users are saying and produce adequate responses, they should also mimic humans in the way they speak.

Researchers at Carnegie Mellon University (CMU) have recently carried out a study aimed at improving how virtual assistants and robots communicate with humans by generating natural gestures to accompany their speech. Their paper, pre-published on arXiv and set to be presented at the European Conference on Computer Vision (ECCV) 2020, introduces Mix-StAGE, a new model that can produce different styles of co-speech gestures that best match the voice of a speaker and what he/she is saying.

“Imagine a situation where you are communicating with a friend in a virtual space through a virtual reality headset,” Chaitanya Ahuja, one of the researchers who carried out the study, told TechXplore. “The headset is only able to hear your voice, but not able to see your hand gestures. The goal of our model is to predict the hand gestures accompanying the speech.”

A team of researchers at Stanford University has created an artificial intelligence-based player called the Vid2Player that is capable of generating startlingly realistic tennis matches—featuring real professional players. They have written a paper describing their work and have uploaded it to the arXiv preprint server. They have also uploaded a YouTube video demonstrating their player.

Video game companies have put a lot of time and effort into making their games look realistic, but thus far, have found it tough going when depicting human beings. In this new effort, the researchers have taken a different approach to the task—instead of trying to create human-looking characters from scratch, they use sprites, which are characters based on video of real people. The sprites are then pushed into action by a computer using artificial intelligence to mimic the ways a human being moves while playing tennis. The researchers trained their AI system using video of real tennis professionals performing; the footage also provided imagery for the creation of sprites. The result is an interactive player that depicts real professional tennis players such as Roger Federer, Serena Williams, Novak Jovovich and Rafael Nadal in action. Perhaps most importantly, the simulated gameplay is virtually indistinguishable from a televised tennis match.

The discovery has led to a new polymer that allows humans to integrate electronics into the brain after challenges with substances such as gold, steel and silicon resulted in scarring of organic tissue.

A major breakthrough in materials research may allow the human brain to link with artificial intelligence, it was announced at an American Chemical Society Fall 2020 event on Monday.

Scarring due to previously used materials can block electrical signals transmitted from computers to the brain, but University of Delaware researchers developed new types of polymers aimed at overcoming the risks.

As we wind up our discussion about the Space Race and touch on the strategies employed by China in its bid to stay on top of space and tech, we delve into the meaty topic of next generation Artificial Intelligence including GPT-3, OpenAI, CommaAI and how they are making strides in the avenues of automation, machine learning and translation and also self driving cars. It’s a brave new world and we discuss some of the many pitfalls of this new emerging range of systems that can come with many issues along with many benefits.

Elon Musk has made a rare new comment about Tesla’s now not-so-secret ‘Dojo’ program to create an AI-training supercomputer and gave a hint of its capacity.

A temperature of 130 degrees Fahrenheit (54.4 degrees Celsius) recorded in California’s Death Valley on Sunday by the US National Weather Service could be the hottest ever measured with modern instruments, officials say.

The reading was registered at 3:41 pm at the Furnace Creek Visitor Center in the Death Valley national park by an automated observation system—an electronic thermometer encased inside a box in the shade.

In 1913, a weather station half an hour’s walk away recorded what officially remains the world record of 134 degrees Fahrenheit (56.7 degrees Celsius). But its validity has been disputed because a superheated sandstorm at the time may have skewed the reading.

Although true “cyborgs”—part human, part robotic beings—are science fiction, researchers are taking steps toward integrating electronics with the body. Such devices could monitor for tumor development or stand in for damaged tissues. But connecting electronics directly to human tissues in the body is a huge challenge. Now, a team is reporting new coatings for components that could help them more easily fit into this environment.

The researchers will present their results today at the American Chemical Society (ACS) Fall 2020 Virtual Meeting & Expo.

“We got the idea for this project because we were trying to interface rigid, inorganic microelectrodes with the brain, but brains are made out of organic, salty, live materials,” says David Martin, Ph.D., who led the study. “It wasn’t working well, so we thought there must be a better way.”
