RelPrism: A Multi-Faceted Pre-training Framework with Self-Generated Tasks for Relational Databases
Researchers have developed RelPrism, a novel framework for self-supervised learning in relational databases. This multi-faceted approach constructs intrinsic, relational, and hybrid attributes from various perspectives and uses multi-granularity clustering to create pseudo-task pools. By exposing representations to diverse information and granularities, RelPrism enhances adaptability for downstream tasks. Experiments show significant improvements in classification and regression performance compared to existing methods. AI
