InstanceBench benchmark launched to diagnose AI model reasoning

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced InstanceBench, a new diagnostic benchmark designed to evaluate referential reasoning and target identity in referring expression segmentation (RES) models. This benchmark includes over 6,000 images and 25,000 human-verified expressions, with a focus on distinguishing between different types of referential logic and separating errors in target selection from mask generation. Initial evaluations on 22 RES models revealed that while the top model achieved 67.1% mIoU, its performance on identity-aware metrics was lower, highlighting target selection as a primary bottleneck. AI

IMPACT This benchmark could lead to more robust AI models capable of better understanding and reasoning about object identity and relationships in images.

    InstanceBench: Diagnosing Referential Reasoning and Target Identity in Referring Expression Segmentation

    arXiv:2610.09478v1 Announce Type: new Abstract: Referring Expression Segmentation (RES) links natural-language descriptions to pixel-level object masks. Yet standard evaluation provides limited insight into instance-level referential reasoning: it does not systematically distingu…
