Sharpening the Ensemble: An SSIM-Aligned Residual Refiner for Brain-MRI Inpainting Post-Processing

A deep ensemble of the two co-first-place 2025 models is formed and a lightweight residual refiner trained on the ensemble's own outputs under an $\ell_1$ loss augmented with a structural-similarity term whose weight $\lambda$ the authors vary, which improves an already strong ensemble without any large-scale retrainin...
