Dual-Margin Embedding for Fine-Grained Long-Tailed Plant Taxonomy

ArXi:2512.18994v2 Announce Type: replace Taxonomic classification of ecological families, genera, and species underpins biodiversity monitoring and conservation. Existing computer vision methods typically address fine-grained recognition and long-tailed learning in isolation. However, additional challenges such as spatiotemporal domain shift, hierarchical taxonomic structure, and previously unseen taxa often co-occur in real-world deployment, leading to brittle performance under open-world conditions.
