Patch-level multi-vector indexes are especially vulnerable, because each vector corresponds to a local region, and an attacker can invert them one by one and reassemble them according to the geometric layout, bypassing the global information compression blurring of whole-page embeddings.

UnverifiedFrom the multi-vector index alone, an attacker can reconstruct pages quite close to the original images and even precisely identify their source documents.72% similarUnverifiedMulti-hop queries need to traverse multiple information nodes in a step-by-step manner, and vector retrieval is ill-suited for such scenarios due to its lack of a relational dimension.71% similarUnverifiedIf the classification target can be detected from local context, using a huge context window only wastes compute.68% similarUnverifiedIn a multi-agent architecture, downstream agents can only obtain summaries and fragments from upstream agents, resulting in significant information loss during transmission.67% similar
