STAGE: Subspace-Targeted Affine Generative Erasure for Text-to-3D Models

Concept erasure suppresses a target concept while preserving behavior on unrelated inputs. Existing closed-form methods were designed for 2D image diffusion and assume a single generative pathway, so one edit must cover geometry and texture at once. Native 3D generators, which synthesize structured 3D representations d...

ORCA: Occlusion-Aware Refinement and Completion for Novel View Synthesis

Novel-view synthesis from a single image is a fundamentally ambiguous problem. As the camera moves away from the input viewpoint, previously hidden regions become visible, exposing missing geometry and holes in the reconstructed scene. Existing methods often rely on generative models to complete such regions. However,...

CertMark: Distortion-Free Multi-Bit Watermarking with Certified Decoding

Leading multi-bit watermarking methods for language models encode messages by biasing the model's next-token probabilities, creating a trade-off between message recovery and text quality. Their decoders typically return the highest-scoring candidate from accumulated token-level evidence, without a certified abstention...

Floating Radiance Networks

Experiments across standard reconstruction benchmarks demonstrate competitive rendering quality while using a compact set of primitives and establish FlaRe as a versatile representation that brings high-fidelity neural rendering, ray-tracing, geometric manipulation, and appearance editing into a unified scene model.

OmniStyle-INR: Universal and Multimodal Style Transfer for INRs

OmniStyle-INR is introduced, a novel framework that leverages network-based continuous representations as a truly universal domain that performs high-quality style transfer across all visual modalities, guided seamlessly by both text prompts and visual exemplars.

GROM: Gradient-Free Rapid One-Shot Machine Unlearning

This work proposes a novel one-shot unlearning approach, abandoning iterative optimization in favor of a direct, exact analytical solution, and achieves state-of-the-art forgetting-utility trade-offs on TOFU-5%, TOFU-10%, MUSE-Books, MUSE-News and WMDP, significantly reducing computational overhead without sacrificing...

TOM-GS: Editable Video Representation via Temporal Opacity Modulation of Static 3D Gaussians

TOM-GS is introduced, an editable video representation that forgoes complex deformations in favor of regular 3D Gaussians equipped with a continuous temporal opacity formulation, which enables static 3D spatial components to fade smoothly in and out of the scene.
