GaussianFormer3D: Multi-Modal Gaussian-Based Semantic Occupancy Prediction with 3D Deformable Attention

ICRA 2026poster

3D semantic occupancy prediction is essential for achieving safe, reliable autonomous driving and robotic navigation. Compared to camera-only perception systems, multi-modal pipelines, especially LiDAR-camera fusion methods, can produce more accurate and fine-grained predictions. Although voxel-base…

PoGDiff: Product-of-Gaussians Diffusion Models for Imbalanced Text-to-Image Generation

NeurIPS 2025poster

Diffusion models have made significant advancements in recent years. However, their performance often deteriorates when trained or fine-tuned on imbalanced datasets. This degradation is largely due to the disproportionate representation of majority and minority data in image-text pairs. In this pape…

Asynchrony-Robust Collaborative Perception via Bird's Eye View Flow

NeurIPS 2023poster

Collaborative perception can substantially boost each agent's perception ability by facilitating communication among multiple agents. However, temporal asynchrony among agents is inevitable in the real world due to communication delays, interruptions, and clock misalignments. This issue causes infor…
