MEDR: Query-Independent Frame Selection via Multi-Signal Event Modeling and Dynamic Rescoring
Xinlei Pu, Weijie Shi, Wen Yang +6
Frame selection is a fundamental component of multimodal large language models, enabling long videos to be processed under limited visual-token and computational budgets. Uniform s…
LoopGuard: Breaking Self-Reinforcing Attention Loops via Dynamic KV Cache Intervention
Dongjie Xu, Hao Wu, Weijie Shi +7
Through systematic experiments on long-context generation, we observe a damaging failure mode in which decoding can collapse into persistent repetition loops. We find that this deg…
Forgetting by Pruning: Data Deletion in Join Cardinality Estimation
Chaowei He, Yuanjun Liu, Qingzhi Ma +4
Machine unlearning in learned cardinality estimation (CE) systems presents unique challenges due to the complex distributional dependencies in multi-table relational data. Specific…
ELASTIC: Efficient Linear Attention for Sequential Interest Compression
Jiaxin Deng, Shiyao Wang, Song Lu +5
State-of-the-art sequential recommendation models heavily rely on transformer's attention mechanism. However, the quadratic computational and memory complexities of self attention…
