    • 摘要: 面向多源异构灾害监测数据,本文提出融合“冲突感知D-S证据融合”与“CNN-LSTM-Attention三重表征”的智能预测与协同调控框架,证据层通过联合建权与折扣回流机制缓解信念极化;表征层融合空间、时序建模与知识注意力,实现多源特征动态加权与语义一致;决策层引入可行域投影与CVaR约束,提升极端工况稳健性与安全性。实验表明,该方法在PR-AUC、召回率等指标上稳定提升,高冲突场景中校准性与可解释性更优,揭示了智能调控优势机理。

       

      Abstract: To address multi-source heterogeneous disaster monitoring data, this paper proposes an intelligent prediction and collaborative control framework integrating "conflict-aware D-S evidence fusion" and "CNN-LSTM-Attention triple representation". At the evidence layer, a joint weighting and discount reflux mechanism alleviates belief polarization; at the representation layer, spatial-temporal modeling and knowledge-guided attention are fused to achieve dynamic weighting and semantic consistency of multi-source features; at the decision-making layer, feasible region projection and CVaR constraints are introduced to enhance robustness and safety under extreme operating conditions. Experimental results demonstrate that the method achieves stable improvements in metrics such as PR-AUC and recall, exhibits superior calibration and interpretability in high-conflict scenarios, and reveals the advantageous mechanism of intelligent control.
