S-EMBER: A Large-Scale Benchmark for Streaming Egocentric Memory Retrieval

Xiaodong Wang, Xuanyi Zhao, Pedro Rodriguez, Devendra Singh Sachan, Barlas Oguz, Seungwhan Moon, et al.

As wearable devices enable continuous first-person recording, AI assistants must reason across long time horizons to recall past experiences-a capability known as episodic memory. Current benchmarks often rely on offline evaluation with access to entire video files, failing to si…

Occlusion-Robust Multi-Object Decoupling for Physics-Based Robotic Interaction

Xin Dong, Lihan Zhang, Tianru Dai, Wenfeng Deng, Yansong Tang

We propose a mask-free method for lossless multi-object 3D reconstruction from sparse and occluded real-world views, enabling physically plausible robotic interaction via Material Point Method (MPM) simulation. Our key insight is that object coupling stems from occlusion and limi…
