What Matters for Lightweight Multi-Label Chest X-Ray Classification? A Controlled Multi-Seed Study of Attention, Loss, Width and Resolution
Attention modules and imbalance-aware losses are often credited with gains in multi-label chest X-ray classification, but their effects are seldom separated from training length, model width, input resolution and seed-to-seed variation. We integrate three existing components, squeeze-and-excitation (SE) channel attenti...
