Progressive-View On-Policy Distillation for Regional-to-Global Transfer in Multimodal LLMs

Regional-to-global distillation uses crop-conditioned guidance to improve full-image understanding. The challenge is to effectively transfer the teacher's crop-based advantage to the student's full-image inference. We propose progressive-view on-policy distillation (PVD), which shifts the student's view distribution fr...

ALLOT: Budgeted Hybrid-Memory Routing for Knowledge Updates in LLMs

For large language models (LLMs), parametric adaptation is costly when retrieval already suffices. We introduce ALLOT, a hybrid-memory routing framework that separates learned write priority from a hard parametric budget. A memory-aware router combines frozen text representations, retrieval confidence, and relation met...

WorldMark: A Plug-and-Play World Knowledge Interface for Cross-Host Language Model Watermarking

WorldMark is introduced, a plug-and-play interface that uses World Knowledge Memory to organize semantic and episodic knowledge in a memory graph, converts the retrieved knowledge into a token-level knowledge saliency score, and adjusts the strength of a host watermark through Asymmetric Knowledge Modulation (AKM).
