3DGS$^2$-TR: A Scalable Second-Order Trust-Region Method for 3D Gaussian Splatting
ICML 2026poster
We propose 3DGS$^2$-TR, a second-order optimizer for accelerating the scene training problem in 3D Gaussian Splatting (3DGS). Unlike existing second-order approaches that rely on explicit or dense curvature representations, such as 3DGS-LM (Höllein et al., 2025) or 3DGS2 (Lan et al., 2025), our meth…
