New pruning method slashes visual document retrieval model size

Researchers have developed Structural Anchor Pruning (SAP), a novel training-free method to compress visual document retrieval models. SAP addresses the significant storage overhead of multi-vector indexes in these models by identifying and pruning redundant visual tokens without requiring query-dependent training. The framework utilizes a Score Retention diagnostic and a visual in-degree centrality scorer to effectively reduce index size while maintaining high retrieval accuracy. AI

IMPACT Introduces a technique to reduce storage costs for visual document retrieval systems, potentially enabling wider deployment.

    Structural Anchor Pruning: Training-Free Multi-Vector Compression for Visual Document Retrieval

    arXiv:2601.20107v2 Announce Type: replace-cross Abstract: Recent Vision-Language Models (e.g., ColPali) enable fine-grained Visual Document Retrieval (VDR) but incur prohibitive multi-vector index storage overhead. Existing training-free pruning methods either rely on heuristic l…
