Fast Autoregressive Video Diffusion and World Models with Temporal Cache Compression and Sparse Attention

ICML 2026poster

Autoregressive video diffusion models enable \emph{streaming} generation, opening the door to long-form synthesis, video world models, and interactive neural game engines. However, their core attention layers become a major bottleneck at inference time: as generation progresses, the KV cache grows, …

EffoVPR: Effective Foundation Model Utilization for Visual Place Recognition

ICLR 2025poster

The task of Visual Place Recognition (VPR) is to predict the location of a query image from a database of geo-tagged images. Recent studies in VPR have highlighted the significant advantage of employing pre-trained foundation models like DINOv2 for the VPR task. However, these models are often deeme…

Find your Needle: Small Object Image Retrieval via Multi-Object Attention Optimization

NeurIPS 2025poster

We address the challenge of Small Object Image Retrieval (SoIR), where the goal is to retrieve images containing a specific small object, in a cluttered scene. The key challenge in this setting is constructing a single image descriptor, for scalable and efficient search, that effectively represents…
