How GaussianPile Enables 3DGS to Reconstruct Internal Structures from Slice‑Based Volumetric Images

GaussianPile extends 3D Gaussian Splatting to slice‑based volumetric data by embedding finite slice thickness and focus depth into the rendering pipeline, achieving up to 20‑26× compression, 8‑minute training, and superior 2D/3D PSNR/SSIM compared with HEVC, INR/NeRF and standard 3DGS on medical imaging datasets.

Learning Adaptive Gaussian Sampling for 3D Generation: Density‑Sampled Gaussians (DeG) at SIGGRAPH 2026

The SIGGRAPH 2026 paper “Generative 3D Gaussians with Learned Density Control” introduces Density‑Sampled Gaussians (DeG), a differentiable framework that lets a model learn where to place Gaussian splats by sampling from a learned spatial density, enabling arbitrary‑budget, non‑uniform 3D representations with higher quality per cost.

Can Tabular Anomaly Detection Move Beyond One‑for‑One? OFA‑TAD Introduces a One‑for‑All Paradigm

Tabular anomaly detection traditionally requires training a separate model for each dataset (one‑for‑one), but the new OFA‑TAD framework trains once on multiple source tables and directly transfers to unseen target tables without fine‑tuning, leveraging multi‑view distance encoding, MoE fusion, and synthetic pseudo‑anomalies to achieve state‑of‑the‑art performance across 34 datasets in 14 domains.
