AutoGrable: What Is a Good Graph for a Table?
Tamara Cucumides, Floris Geerts
Graph learning presupposes a graph, and tables and relational databases do not come with one. Applying a GNN to them requires deciding which entities become nodes, which of them to…
Latent Bridges for Multi-Table Question Answering
Simone Varriale, Tamara Cucumides, Floris Geerts +1
We introduce GRAB, a constructor-encoder-bridge pipeline for table question answering. Our method lifts relational data into an heterogeneous graph, encodes it via message passing,…
Grables: Tabular Learning Beyond Independent Rows
Tamara Cucumides, Floris Geerts
Tabular learning is still dominated by row-wise predictors that score each row independently, which fits i.i.d. benchmarks but fails on transactional, temporal, and relational tabl…
From Features to Structure: Task-Aware Graph Construction for Relational and Tabular Learning with GNNs
Tamara Cucumides, Floris Geerts
Tabular and relational data remain the most ubiquitous formats in real-world machine learning applications, spanning domains from finance to healthcare. Although both formats offer…
