PUP 3D-GS: Principled Uncertainty Pruning for 3D Gaussian Splatting
Alex Hanson, Allen Tu, Vasu Singla, Mayuka Jayawardhana, Matthias Zwicker, Tom Goldstein
arXiv, 2024
code | website | bibtex

We find that the sensitivity of a Gaussian to the L2 loss across the scene -- captured as as a second order approximation -- is a surprisingly effective pruning score.

Matthew Gwilliam, Srinidhi Hegde, Lade Tinubu,  Alex Hanson
ICCV Workshops, 2021 (Oral)
code | bibtex

Training on some skewed race distributions of a popular training dataset to mitigate racial bias produces more equitable models.
