New ARENA model offers interpretable solar flare prediction

Researchers have developed a new neural network architecture called ARENA (Active Region attENtion Aggregation) for predicting solar flares. This model utilizes multiple-instance learning and weak supervision, requiring only a flare or no-flare label for an observation. ARENA's attention mechanism identifies the most relevant active region for prediction without needing explicit origin annotations, achieving a Heidke Skill Score of 0.45, which is competitive with existing methods.
