New EHHN model advances next activity prediction for object-centric event logs

Researchers have developed EHHN, a novel Event-driven Heterogeneous Hypergraph Network designed for next activity prediction in object-centric event logs. This new model addresses limitations in existing methods by effectively capturing cross-object context, event-driven object state changes, inter-event timing, and global execution patterns. Experiments demonstrate that EHHN outperforms nine baseline methods across four benchmarks, achieving significant improvements in accuracy and macro F1-score while also substantially reducing GPU memory usage. AI
