arXiv:2607. 05522v1 Announce Type: cross Abstract: 3D Gaussian splatting (3DGS) is a strong representation for real-time novel-view synthesis, but its standard training pipeline relies on point estimates and hand-tuned heuristics, providing no native uncertainty or principled complexity control.

Hierarchical Incremental Beta Splatting (HIBS) introduces beta kernels into online 3D Gaussian splatting, allowing the shape parameter to interpolate between soft Gaussian-like primitives and flat-topped, near-opaque surfels. This confidence-aware spawning uses geometric observability and multi-view depth agreement to initialize opacity and shape, producing solid primitives where geometry is verifiable and soft, correctable primitives elsewhere. HIBS also employs error-driven relocation for densification, bounded beta kernel support for efficient culling and rasterization, and a shape-preserving merging formulation to create a level-of-detail hierarchy, achieving up to 0.8 dB PSNR improvement and 40 % faster optimization on the Mip-NeRF 360 dataset.

3D Gaussian Splatting (3DGS) renders novel views in real time, but an uncertainty heatmap does not certify that a rendered view meets a certain prediction coverage. We treat novel-view synthesis as st...
Repeated evaluation can estimate a benchmark score accurately while still requiring replication to certify narrow uncertainty. We characterize that requirement on a fixed grid of $M$ tasks with $L$ binary paths per task under the hard budget $(M+t)K$, where each path costs at most $K$ responses or episodes.
