GROVE adds layered memory for streaming video assistants
The training-free framework shares one video memory for reactive QA and proactive assistance.
Why it matters
The work points to memory architectures as a key lever for wearable and video-language assistants, where models must use past visual evidence before future questions are known. It also shows growing interest in improving Video-LLM behavior without changing the underlying model.
The key points
- 1.GROVE builds temporal memory from continuous video streams.
- 2.It supports both reactive QA and proactive assistance.
- 3.ObjectStream uses latent objects as persistent video-memory anchors.
Researchers introduced GROVE, a training-free framework for streaming video experience that builds memory causally from a continuous video stream. The system keeps fine-grained perceptual evidence and consolidates it into time-stamped moments, coherent episodes and recurring cross-day patterns, with retrieval skills matched to each level. The authors report that GROVE achieved the best results among compared methods on multiple benchmarks, including MM-lifelong and EgoServe. A related arXiv paper, ObjectStream, also targets streaming video understanding with training-free memory, using latent objects as persistent anchors.
