How to Use a PINN for a Navier-Stokes Inverse Problem

# AI Can Now Diagnose Artery Problems From Just a Few Noisy Measurements Researchers have shown that AI can figure out what's happening inside a narrowed artery—like blood flow speed and vessel stiffness—using only 40 imperfect sensor readings, which is far fewer measurements than traditional methods would require. This matters for doctors because it means they could potentially diagnose dangerous blockages or abnormalities with simpler, less invasive tests. The technique teaches AI to respect the laws of physics while making sense of messy, real-world data.
