Neural-network emulators trained on roughly 100,000 to 1,000,000 Grad-Shafranov equilibria can generate virtual circuits with 5-10% displacement accuracy, and shaping currents can be inferred online with few-Ampere residuals.

Real-Time Applicability of Emulated Virtual Circuits for Tokamak Plasma Shape Control
Neural-network emulators trained on roughly 100,000 to 1,000,000 Grad-Shafranov equilibria can generate virtual circuits with 5-10% displacement accuracy, and shaping currents can be inferred online with few-Ampere residuals.
