The head scientist for Alexa thinks the old benchmark for computing is no longer relevant for today’s AI era.
Albert Einstein once said, “You have to learn the rules of the game, and then you have to play better than anyone else.” That could well be the motto at DeepMind, as a new report reveals it has developed a program that can master complex games without even knowing the rules.
DeepMind, a subsidiary of Alphabet, has previously made groundbreaking strides using reinforcement learning to teach programs to master the Chinese board game Go and the Japanese strategy game Shogi, as well as chess and challenging Atari video games. In all those instances, computers were given the rules of the game.
But Nature reported today that DeepMind’s MuZero has accomplished the same feats—and in some instances, beat the earlier programs—without first learning the rules.
Over the past few years, artificial intelligence (AI) tools, particularly deep neural networks, have achieved remarkable results on a number of tasks. However, recent studies have found that these computational techniques have a number of limitations. In a recent paper published in Nature Machine Intelligence, researchers at Tübingen and Toronto universities explored and discussed a problem known as ‘shortcut learning’ that appears to underpin many of the shortcomings of deep neural networks identified in recent years.
“I decided to start working on this project during a science-related travel in the U.S., together with Claudio Michaelis, a dear colleague and friend of mine,” Robert Geirhos, one of the researchers who carried out the study, told TechXplore. “We first attended a deep learning conference, then visited an animal research laboratory, and finally, a human vision conference. Somewhat surprisingly, we noticed the very same pattern in very different settings: ‘shortcut learning,’ or ‘cheating,’ appeared to be a common characteristic across both artificial and biological intelligence.”
Geirhos and Michaelis believed that shortcut learning, the phenomenon they observed, could explain the discrepancy between the excellent performance and iconic failures of many deep neural networks. To investigate this idea further, they teamed up with other colleagues, including Jörn-Henrik Jacobsen, Richard Zemel, Wieland Brendel, Matthias Bethge and Felix Wichmann.
Movie ratings can determine a movie’s appeal to consumers and the size of its potential audience. Thus, they have an impact on a film’s bottom line. Typically, humans do the tedious task of manually rating a movie based on viewing the movie and making decisions on the presence of violence, drug abuse and sexual content.
Now, researchers at the USC Viterbi School of Engineering, armed with artificial intelligence tools, can rate a movie’s content in a matter of seconds, based on the movie script and before a single scene is shot. Such an approach could allow movie executives the ability to design a movie rating in advance and as desired, by making the appropriate edits on a script and before the shooting of a single scene. Beyond the potential financial impact, such instantaneous feedback would allow storytellers and decision-makers to reflect on the content they are creating for the public and the impact such content might have on viewers.
Using artificial intelligence applied to scripts, Shrikanth Narayanan, University Professor and Niki & C. L. Max Nikias Chair in Engineering, and a team of researchers from the Signal Analysis and Interpretation Lab (SAIL) at USC Viterbi, have demonstrated that linguistic cues can effectively signal behaviors on violent acts, drug abuse and sexual content (actions that are often the basis for a film’s ratings) about to be taken by a film’s characters.
With the rapid advancement of humanoid robots in the market today, we’re able to see how our lives have become simpler and easier. In this video let’s look at some of the most advanced humanoid robots that are being developed by various companies and organisations.

Volkswagen shows mobile charging robot for fully autonomous charging of electric vehicles.
A year ago, Volkswagen unveiled its mobile charging station concept in which an autonomous robot facilitates the charging of the battery of electric cars. And now, after spending a year making the concept a reality, the automaker gives us a first glimpse of the prototypes of its mobile charging robot.
The first working prototypes, able to revolutionize the world of electric cars, has always been linked to the current scarcity of charging infrastructures. Its task – fully autonomous charging of vehicles in restricted parking areas, like underground car parks.

Nearly two years ago, Chmielewski underwent a 10-hour brain surgery at the Johns Hopkins Hospital in Baltimore as part of a clinical trial originally spearheaded by the Defense Advanced Research Projects Agency and leveraging advanced prosthetic limbs developed by the Johns Hopkins Applied Physics Laboratory. Its goal was to allow participants to control [assistive devices](https://medicalxpress.com/tags/assistive+devices/), and enable perception of physical stimuli (touching the limbs) using neurosignals from the brain. Surgeons implanted six electrode arrays into both sides of his brain, and within months he was able to demonstrate, for the first time, simultaneous control of two of the [prosthetic limbs](https://medicalxpress.com/tags/prosthetic+limbs/) through a brain-machine interface developed by APL.
For more than 30 years—following an accident in his teens—Robert “Buz” Chmielewski has been a quadriplegic with minimal movement and feeling in his hands and fingers. But last month he was able to manipulate two prosthetic arms with his brain and feed himself dessert.
Buz’s accomplishment marks a big step toward restoring function and autonomy for patients affected by an illness or injury that results in the partial or total loss of use of all four limbs and torso.

In a test with 12 students, Irony Man was deemed more likable than conventional robots. But Irony Man’s inability to know when to use irony could backfire.
“The robot is not yet able to determine whether and when there is a good moment to employ irony,” André said. “It may happen that the robot generates a funny utterance, but the user is irritated.”
