Heteroscedastic Neural Surrogate Modeling for Robust and Rapid Bayesian Inference in Fusion Plasma Diagnostics

This work proposes a neural-network-based probabilistic surrogate framework for rapid and robust MCMC inference that achieves>1500x acceleration over exact physical forward models, while simultaneously reducing inference error (RMSE) by>20% compared to standard homoscedastic neural baselines, offering a highly promisin...

Magnetic field reconstruction from proton radiography via physics-guided out-of-distribution filtering

Reconstructing multidimensional vector fields from path-integrated projection data is a fundamental challenge in high-energy-density physics, particularly when experimental sources exhibit spectral broadening and shot-to-shot jitter. We present a physics-guided deep-learning framework that addresses this ill-posed inve...
