Stage-wise collaborative feature enhancement for accurate maize insect pest detection in complex agricultural scenes

Accurate maize pest detection is hindered by morphological similarity among pest categories, complex backgrounds, and the loss of spatial detail in small targets To address these challenges, we developed a stage-wise collaborative feature enhancement framework based on RT-DETR-R18. A Similarity-aware Decoupl...

Hidden Boundary Motion in Transformer Optimization: Function-Space Orthogonalization of Affine Weight and Bias Updates

A diagnostic optimizer, Shape--Boundary Orthogonal AdamW (SBO-AdamW), is implemented that optimizes g_W-g_b\mu^\top and g_b with independent Adam states and compensates the weight-induced boundary displacement and a stable centered-affine parameterization is identified as the required next step.
