Researchers detect hidden threats with advanced X-ray imaging

Researchers have combined various X-ray imaging technologies to create multi-contrast images that can be used to detect threatening materials such as explosives in thousands of complicated scenarios. The new approach, which ...

AI trained to draw inspiration from images, not copy them

Powerful new artificial intelligence models sometimes, quite famously, get things wrong—whether hallucinating false information or memorizing others' work and offering it up as their own. To address the latter, researchers ...

AI chips could get a sense of time with memristor that can be tuned

Artificial neural networks may soon be able to process time-dependent information, such as audio and video data, more efficiently. The first memristor with a "relaxation time" that can be tuned is reported today in Nature ...

Can we rid artificial intelligence of bias?

Artificial intelligence built on mountains of potentially biased information has created a real risk of automating discrimination, but is there any way to re-educate the machines?
