About

Content & Construction: The document introduces VHop, a controllable setting for studying multi-hop visual retrieval in latent space. It connects images via shared objects to create trajectories with varying hop counts, object distractors, and task difficulties (Table 1). A flexible data generation framework provides verified ground-truth labels satisfying detailed query instructions.

Scoring & Findings: The benchmark evaluates retrievers on success rates across different difficulty levels defined by hops, corpus size, etc. Experiments show VHop-Router boosts retrieval performance from under 5% to 76.3%, improving agentic search task success rates by 52.7% and reducing token length significantly compared to baselines.
