MetaSieve is a metapath selection layer that reduces subgraph size in relational deep learning by pruning uninformative metapaths using SQL join and aggregation statistics. It scores candidate metapath extensions with a lightweight function that favors informative yet lightweight paths, discarding those below a threshold. The method is independent of GNN parameters and, when applied to the RelBench benchmark, consistently cuts per‑epoch training time while preserving or improving accuracy.

InRTL: Effective Intra-Inter Interaction Learning for Relational Tables proposes a unified framework that explicitly models dependencies both within and across relational tables. The approach introduces intra-table interactions to capture associations among rows in the same table and inter-table interactions to capture dependencies between rows linked by primary key–foreign key relationships. It employs a column-aware table encoder, Transformer-based self-attention and cross-attention modules, and incorporates linearized attention and heterogeneous graph neural networks to improve scalability, demonstrating effectiveness across ten datasets and 24 real-world tasks.

arXiv:2606. 08491v1 Announce Type: new Abstract: Relational deep learning (RDL) converts relational databases (RDBs) into heterogeneous graphs, but graphs derived directly from database schemas are often not well suited for how graph neural networks (GNNs) perform relational reasoning.
