With some help from AI, your next move can be predicted

AI might know where you’re going before you do. Researchers at Northeastern University used large language models, the kind of advanced artificial intelligence normally designed to process and generate language, to predict human movement.

How RHYTHM predicts human movement
RHYTHM, their innovative tool, “can revolutionize the forecasting of human movements,” forecasting “where you’re going to be in the next 30 minutes or the next 25 hours,” said Ryan Wang, an associate professor and vice chair of research in civil and environmental engineering at Northeastern.

The hope is that RHYTHM will improve domains like transportation and traffic planning to make our lives easier, but in extreme cases, RHYTHM could even be deployed to respond to natural dis...

AI-powered intelligent 6G radio access technology significantly enhances wireless communication performance

ETRI develops AI-powered intelligent 6G radio access technology that significantly enhances wireless communication performance

Korea’s research community has reached an important milestone on the path toward next-generation mobile communications with the development of a technology platform that brings the 6G era closer. Researchers expect that AI-Native mobile networks, in which artificial intelligence autonomously controls and optimizes the communication system, could achieve transmission efficiencies up to 10 times higher than those of 5G.

Breakthroughs in AI-based wireless access
ETRI has completed the development of AI-based wireless access technology (AI-RAN), a core foundational technology for the 6G era, and has achieved significant results in paving the way for the AI-based next-generation mobile communication era.

The biggest feature of this technology is that it has applied AI to wireless tran...

Sudden breakups of monogamous quantum couples surprise researchers

two layers of a chemical structure lie above each other with black balls hovering on top. On the top layer, there is a cyan ball with a white ball in the corresponding layer below
An exciton forms when an electron pairs up with a hole—a mobile particle-like void in a material where an electron is missing from an atom. When paired up as an exciton, a hole and electron normally travel around together as an exclusive couple, but a new experiment probes what happens when conditions in a material break up the pair. In the image, a hole (grey sphere) resides in the bottom layer of a stacked material and is paired to an electron in the top layer (cyan sphere). None of the electrons present in the top layer (black spheres) are willing to share a spot in the material with each other or the electron in the exciton. (Credit: Mahmoud Jalali Mehrabad/JQI)
