Researchers from DS@GT ARC have developed a multi-stage system for the FathomNetCLEF 2026 competition, which involves underwater object detection and marine species classification. Their approach addresses challenges of sparse training labels and out-of-distribution test data by using a frozen Megalodon YOLOv8x detector for proposal generation and a LoRA-finetuned DINOv3 ViT-H classifier for species identification. The system achieved 12th place out of 102 teams by employing a weighted fusion of detector and classifier confidence scores, alongside proxy datasets for validation. AI
IMPACT This research demonstrates advanced techniques for object detection and classification in challenging, real-world scenarios, potentially improving marine biodiversity monitoring.
RANK_REASON The cluster contains an academic paper detailing a novel AI system for a specific detection and classification task. [lever_c_demoted from research: ic=1 ai=1.0]
