AgroMM-GSF++: Confidence-Adaptive Lightweight Multimodal Fusion for Plant Disease Recognition with Repeated Multi-Seed Cross-Validation and External Benchmarking

Abstract

Abstract Recent multimodal agricultural research emphasizes large-scale vision-language systems, while lightweight reproducible approaches remain underexplored for constrained deployments. We present AgroMM-GSF++, a compact image-text fusion framework for plant disease recognition. The model combines a small visual backbone and text-prototype branch with confidence-adaptive gating. To strengthen empirical evidence, we run repeated multi-seed stratified cross-validation (three seeds, repeated folds) and include stronger pretrained transfer baselines (EfficientNet-B0 and ViT-B/16 fine-tunes). We further evaluate on an external PlantVillage subset to test cross-dataset robustness under the same protocol family. On beans, transfer baselines lead absolute macro-F1 (EfficientNet-B0-FT: 0.6355±0.0340), while AgroMM-GSF++ reaches 0.5891±0.0552 with much lower latency than transfer models (9.80 vs 205.66 ms/image for EfficientNet-B0-FT). On the external subset, AgroMM-GSF++ improves over fixed lightweight fusion (0.8719 vs 0.8608 macro-F1) while remaining below transfer-heavy baselines. We provide an end-to-end reproducible workspace including scripts, datasets, figures, and camera-ready tables.
