ClueTracer: Question-to-Vision Clue Tracing for Training-Free Hallucination Suppression in Multimodal Reasoning

ClueTracer is a training‑free, parameter‑free plugin that suppresses hallucinations in multimodal reasoning models by tracing how visual clues propagate from the question through the model’s reasoning pathway. It localizes task‑relevant image patches while ignoring irrelevant regions, thereby addressing the problem of reasoning drift where models over‑focus on question‑irrelevant entities. The method improves performance across various reasoning architectures by an average of 1.21× on reasoning benchmarks.

Representing the Unseen: Rethinking Visual Imagination for Spatial Reasoning

The paper introduces ImagiRep, a benchmark that tests spatial reasoning using seven question types across two settings, offering RGB and six alternative representations of imagined states. It shows that accurate RGB generation does not guarantee correct spatial reasoning and that different questions benefit from different representations such as depth, panoramic views, or top‑down geometry. Building on these insights, the authors present GEARS, a lightweight strategy that adaptively selects representations at test time, outperforming existing methods and demonstrating that reasoning about unseen states requires more than just RGB generation.
