SCoOP: Semantic Consistent Opinion Pooling for Uncertainty Quantification in Multiple Vision-Language Model Systems

Dimensions overall score 7.0

• A training-free framework to quantify uncertainty and detect hallucinations in multi-Vision-Language Model systems, improving reliability with minimal overhead. We propose SCoOP (Semantic-Consistent Opinion Pooling), a training-free uncertainty quantification (UQ) framework multi-VLM systems through uncertainty-weighted linear opinion pooling.problem 35%

• ScienceToStartup currently rates this 7.0/10 on the public viability pass. On ScienceQA, SCoOP achieves an AUROC of 0.866 for hallucination detection, outperforming baselines (0.732-0.757) by approximately 10-13%. Code availability is flagged in the production record; the public repository link still needs proof alignment.result 35%
