英文摘要In this work, we develop, for the first time, a supervised classification framework with class-dependent rewards (CDR) to predict >= M flares within 24 h. We construct multiple data sets, covering knowledge-informed features and line-of-sight (LOS) magnetograms. We also apply three deep learning models (CNN, CNN-BiLSTM, and Transformer) and three CDR counterparts (CDR-CNN, CDR-CNN-BiLSTM, and CDR-Transformer). First, we analyse the importance of LOS magnetic field parameters with the Transformer, then compare its performance using LOS-only, vector-only, and combined magnetic field parameters. Second, we compare flare prediction performance based on CDR models versus deep learning counterparts. Third, we perform sensitivity analysis on reward engineering for CDR models. Fourth, we use the SHAP method for model interpretability. Finally, we conduct performance comparison between our models and NASA/CCMC. The main findings are: (1) Among LOS feature combinations, R_VALUE and AREA_ACR consistently yield the best results. (2) Transformer achieves better performance with combined LOS and vector magnetic field data than with either alone. (3) Models using knowledge-informed features outperform those using magnetograms. (4) While CNN and CNN-BiLSTM outperform their CDR counterparts on magnetograms, CDR-Transformer is slightly superior to its deep learning counterpart when using knowledge-informed features. Among all models, CDR-Transformer achieves the best performance. (5) The predictive performance of the CDR models is not overly sensitive to the reward choices. (6) Through SHAP analysis, the CDR model tends to regard TOTUSJH as more important, while the Transformer tends to prioritize R_VALUE more. (7) Under identical prediction time and active region number, the CDR-Transformer shows superior predictive capabilities compared to NASA/CCMC.
