H3Former framework enhances fine-grained visual classification with hypergraph and hyperbolic loss

Researchers have developed H3Former, a novel framework for Fine-Grained Visual Classification (FGVC) that addresses limitations in existing methods. H3Former utilizes a Semantic-Aware Aggregation Module (SAAM) to construct a weighted hypergraph among tokens, capturing high-order semantic dependencies and aggregating them into region-level representations. The framework also incorporates a Hyperbolic Hierarchical Contrastive Loss (HHCL) to enforce hierarchical semantic constraints in a non-Euclidean space, enhancing inter-class separability and intra-class consistency. Experiments on standard FGVC benchmarks demonstrate H3Former's superior performance. AI
