用逻辑规则提升事件预测,让模型既准又合规。

Neuro-Symbolic Learning for Predictive Process Monitoring via Two-Stage Logic Tensor Networks with Rule Pruning

  • 先学数据后精简规则,避免逻辑约束干扰预测
  • 在真实数据集上准确率提升,尤其在合规样本少时更优
  • 适合金融、医疗等需严格遵守流程的领域

序列事件数据的预测建模对欺诈检测和医疗监控至关重要。现有数据驱动方法从历史数据中学习相关性,但无法融入特定于领域的序列约束和事件关系逻辑规则,限制了准确性和合规性。例如,医疗操作必须按特定顺序执行,金融交易须符合合规规则。我们提出一种神经符号方法,通过逻辑网络(LTNs)将领域知识作为可微分逻辑约束集成。采用线性时序逻辑和一阶逻辑形式化控制流、时间和数据内容知识。关键贡献是两阶段优化策略,解决LTNs倾向于满足逻辑公式而牺牲预测精度的问题:预训练阶段使用加权公理损失优先学习数据,随后基于满足动态进行规则剪枝,保留一致且有贡献的公理。在四个真实事件日志上的评估表明,注入领域知识显著提升预测性能,两阶段优化对知识有效利用至关重要(无此优化,知识反而降低性能)。该方法在合规约束强且合规训练样本有限的场景下表现尤为出色,优于纯数据驱动基线,同时确保符合领域约束。

原文摘要 · Abstract (English)

Predictive modeling on sequential event data is critical for fraud detection and healthcare monitoring. Existing data-driven approaches learn correlations from historical data but fail to incorporate domain-specific sequential constraints and logical rules governing event relationships, limiting accuracy and regulatory compliance. For example, healthcare procedures must follow specific sequences, and financial transactions must adhere to compliance rules. We present a neuro-symbolic approach integrating domain knowledge as differentiable logical constraints using Logic Networks (LTNs). We formalize control-flow, temporal, and payload knowledge using Linear Temporal Logic and first-order logic. Our key contribution is a two-stage optimization strategy addressing LTNs' tendency to satisfy logical formulas at the expense of predictive accuracy. The approach uses weighted axiom loss during pretraining to prioritize data learning, followed by rule pruning that retains only consistent, contributive axioms based on satisfaction dynamics. Evaluation on four real-world event logs shows that domain knowledge injection significantly improves predictive performance, with the two-stage optimization proving essential knowledge (without it, knowledge can severely degrade performance). The approach excels particularly in compliance-constrained scenarios with limited compliant training examples, achieving superior performance compared to purely data-driven baselines while ensuring adherence to domain constraints.
