The thousands of cameras are a key feature of the lab, which officially opens inside this 50,000-square-foot store on Thursday. Walmart envisions using them, combined with other technology like sensors on shelves, to monitor the store in real time so its workers can quickly react to replenish products or fix other problems. The technology, shown to The Associated Press, will also be able to track when shelves need to be restocked or if shopping carts are running low. It can spot spills on the floor and even detect when cash registers need to be opened up before long lines start forming.

From Musk's vantage point, Tesla has a huge advantage over autonomous vehicle competitors because it gathers a massive amount of data in the real world. This quarter, he said Tesla will have 500,000 vehicles on the road, each equipped with eight cameras, ultrasonic sensors and radar gathering data to help build the company's neural network, which will serve as the digital equivalent of the self-driving cars' consciousness.

Gross spent 43 years on the faculty of Princeton's psychology department where the university credited him with revolutionizing understanding of sensory processing and pattern recognition. Princeton called his work "foundational to the field of cognitive neuroscience" when he retired in 2013.

BRUSSELS (Reuters) - Companies working with artificial intelligence need to install accountability mechanisms to prevent it being misused, the European Commission said on Monday, under new ethical guidelines for a technology open to abuse by authoritarian regimes.

"Issuing large fines and hitting companies with bigger legal threats is taking a 20th century bullwhip approach to a problem that requires a nuanced solution," he said. "It needs machine learning tools to manage the 21st century problems of the internet, combined with the courage and foresight to establish independent frameworks that preserve the freedoms societies enjoy in the physical world, as well as the online one."

The new cabling will provide a backup power circuit for the station's Canadian-made robot arm and expand wireless communications. The battery work involves re-installing two old batteries. One of the six new lithium-ion batteries doesn't work, and so the outdated pair made of nickel hydrogen need to go back into the slot.

"Ethical AI" has become a new corporate buzz phrase, slapped on internal review committees, fancy job titles, research projects and philanthropic initiatives. The moves are meant to address concerns over racial and gender bias emerging in facial recognition and other AI systems, as well as address anxieties about job losses to the technology and its use by law enforcement and the military.

Hyundai, the world's 5th largest automaker together with affiliate Kia Motors, has been fostering partnerships with self-driving tech and social media firms as it aims to introduce highly automated vehicles by 2020 and fully autonomous vehicles by 2030.

The maker of the Camry sedan, Prius hybrid and Lexus luxury models has shown off various robots, including one that played a violin. Another, resembling R2-D2 of Star Wars, slides around and picks up things. At Monday's demonstration, it handed the basketball to Cue 3.

"We can bring analytics students into this to figure the best way to analyze the environmental data," she said. "The college also has robust environmental studies and science programs that also are interested in this and could benefit from the data as well. There's potential for a number of our students to plug in and do some work on this."
