Never Look Back: Understanding Persistence in 3D Object Memory from Egocentric Videos

Shravan Chaudhari, William Paul, Suchi Saria وآخرون · 2026

As we move through the world and carry out everyday tasks, we encounter objects that may become relevant only later. We are capable of recalling where we left something or what was inside a container, even without knowing we would need it later. Here, we study how an embodied assistant can build a similar memory from e …

Less Context, Better Geometry: Masked Geometric Encoder for Robust 3D Foundation Models

Zhimin Shao, Xijun Liu, Zhaoliang Zhang وآخرون · 2026

Recent progress in 3D foundation models has enabled rapid 3D reconstruction and camera calibration by leveraging learned 3D priors from vast amount of spatial data. However, the all-to-all global attention design leads to quadratic complexity and limits long-sequence inference; unconstrained cross-view interactions als …

Linguistic Loopholes in LLM Unlearning: From a 174-Language Benchmark to Coverage-Aware Unlearning

Unlearning a fact in one language does not guarantee its removal in others as changing the query or even the requested answer language can reopen seemingly forgotten knowledge -- a cross-lingual loophole. The most straightforward solution to this challenge -- unlearning in all languages -- is neither scalable nor desir …
