关系型深度学习(RDL)将多表数据库视为时序异构图,实现端到端表征学习。然而,现有RDL评估普遍依赖静态、单阶段数据快照,忽视了真实数据库的连续演化特性。因此,当前基准无法反映模型随新数据积累而表现的变化。为解决此问题,我们提出一种增量式、多阶段评估与训练范式,以评估并提升先进RDL模型的时间鲁棒性与适应能力。基于大规模基准数据集,我们分析数据演化与模型训练动态,发现多数预测任务均存在时间概念漂移。我们设计多种增量训练策略,并验证迁移学习在RDL场景中既可行又高效。结合新的时序评估指标(侧重近未来预测准确性),结果表明增量微调模型始终优于昂贵的从头训练基线。

原文摘要 · Abstract (English)

Relational Deep Learning (RDL) models multi-tabular databases as temporal heterogeneous graphs to enable end-to-end representation learning. However, prevailing RDL evaluation practices rely on static, single-episode dataset snapshots, overlooking the continuous, time-evolving nature of real-world databases. Consequently, current RDL benchmarks fail to capture how model performance changes as new data accumulates over time. To address this limitation, we introduce an incremental, multi-episode evaluation and training paradigm to assess and improve the temporal robustness and adaptability of state-of-the-art RDL models. Using established large-scale datasets, we examine data evolution and model training dynamics, demonstrating that temporal concept drifts occur in the majority of predictive tasks. We present multiple incremental training regimes for fine-tuning the models and demonstrate that transfer learning is both feasible and highly effective in the RDL setting. Alongside a new temporal evaluation metric that prioritizes near-future accuracy, we show that our incrementally fine-tuned models consistently outperform the standard, expensive, from-scratch trained baselines.
