Overfitting Mitigation via Singular Value Decomposition in Minimum Bayes Risk Decoding
This is a solid technique for a real problem: MBR decoding tends to overfit to whichever metric you optimize for. The SVD denoising approach is clever and shows measurable gains. The catch is that MBR is not standard practice yet for most generation systems. This matters if you're already using MBR and hitting metric overfitting; otherwise, it's academic refinement.
