Invisible danger in the atmosphere?!
This is Sandra Tsing Loh with the Loh Down on Science saying…
YOLO!!!…or… “You Only Live Once.”
Less actually, if you inhale too many aerosols! These are chemical molecules clustered in the atmosphere. They’re bad for our climate and health. We have ways of monitoring them, but they move fast. How can we keep an eye on them?
Rajat Bhandari and team at the Indian Institute of Technology say the answer is… the YOLO algorithm! But this one means “You Only LOOK Once.”
YOLO was trained and tested with data from past aerosol events, and it identifies new ones with NINETY-SEVEN percent accuracy!
With YOLO, scientists can track atmospheric threats faster.
Because, after all… you only live ONCE.
