Multi-granularity Adaptive Hypergraph Representation Learning via Granular-ball

A novel framework called Adaptive Granular Hypergraph Generation (MGHRL) is introduced, which generates hyperedges at multiple levels of granularity through the adaptive splitting of granular-ball, effectively capturing high-order relationships based on the graph's topological structure.

Selective Constraint Learning for Unsupervised Cross-Domain Image Retrieval

This work proposes Selective Constraint Learning (SCL), a framework that introduces external semantic guidance as a stable prior for unsupervised cross-domain image retrieval and designs a generic constraint loss to jointly facilitate intra-domain compactness and inter-domain alignment.
