Abstract: 3D Gaussian Splatting enables high-quality real-time rendering but often
produces millions of splats, resulting in excessive storage and computational
overhead. We propose a novel lossy compression method based on learnable
confidence scores modeled as Beta distributions. Each splat's confidence is
optimized through reconstruction-aware losses, enabling pruning of
low-confidence splats while preserving visual fidelity. The proposed approach
is architecture-agnostic and can be applied to any Gaussian Splatting variant.
In addition, the average confidence values serve as a new metric to assess the
quality of the scene. Extensive experiments demonstrate favorable trade-offs
between compression and fidelity compared to prior work. Our code and data are
