Contextual Memory-Enhanced Source Coding for Low-SNR Communications
Ziqiong Wang, Rongpeng Li, Zhifeng Zhao +1
Separate Source-Channel Coding (SSCC) remains vulnerable in noisy text transmission due to the fragility of autoregressive source decoding, especially when Arithmetic Coding (AC) r…
Physics-Gated Visual Prediction of MARFE on the HL-3 Tokamak
Qianyun Dong, Rongpeng Li, Zongyu Yang +5
The Multifaceted Asymmetric Radiation From the Edge (MARFE) is a critical plasma instability that often precedes density-limit disruptions in tokamaks, posing a significant risk to…
Plasma Shape Control via Zero-shot Generative Reinforcement Learning
Niannian Wu, Rongpeng Li, Zongyu Yang +6
Traditional PID controllers have limited adaptability for plasma shape control, and task-specific reinforcement learning (RL) methods suffer from limited generalization and the nee…
FusionMAE: large-scale pretrained model to optimize and simplify diagnostic and control of fusion plasma
Zongyu Yang, Zhenghao Yang, Wenjing Tian +14
In magnetically confined fusion device, the complex, multiscale, and nonlinear dynamics of plasmas necessitate the integration of extensive diagnostic systems to effectively monito…
