IDP-PGFE: an interpretable disruption predictor based on physics-guided feature extraction
Disruption prediction has made rapid progress in recent years, especially in machine learning (ML)-based methods. If a disruption prediction model can be interpreted, it can tell why certain samples are classified as disruption precursors. This allows us
