Generative Regularization for Robust Extrapolation
DynaGen employs a conditional diffusion process to overcome cognitive generalization bias in extrapolation. This forces the model to learn underlying evolutionary principles rather than superficial patterns.
SSAE produces initial structural representation (z_i)
→
Forward Diffusion corrupts z_i with Gaussian noise (z_k)
→
Denoising Network predicts noise (ε_θ) based on corrupted z_k, query relation, and time
→
Model learns underlying generative principles of TKG evolution
→
Enhances ability to predict unseen future events (robust extrapolation)

Performance Across 6 Benchmark Datasets
DynaGen consistently achieves state-of-the-art results across all six benchmark datasets for both interpolation and extrapolation reasoning tasks, demonstrating its superior ability to capture complex temporal dynamics and generalizable patterns.
Qualitative Insights from Case Studies
Case studies demonstrate DynaGen's strong reasoning capabilities for both interpolation and extrapolation. It accurately ranks correct entities and handles both frequent and rare event patterns, showing sensitivity to temporal context and generalization to unseen time points.
Interpolation on YAGO (Case 1 & 2)
For query (S:88, P:4, O:1668) in 2006, DynaGen ranks correct S/O first. For (S:349, P:8, O:7694) in 2000, correct S/O are within top 5, demonstrating robust reasoning for complex relationships.
Extrapolation on ICEWS05-15 (Case 3 & 4)
For 'Police (Sudan), Arrest, Citizen (Sudan)' in 2015-05-21, S/O ranked first. For 'China, Express intent to meet, Japan' in 2007-03-20, S/O also ranked first. Shows effective projection of recurring patterns and plausible alternatives.
