arXiv (cs.CL) (Research): check the dataset, evaluation setup, and adoption assumptions for Knowledge Management.
Standard benchmarks for multimodal large language models (MLLMs) score each item on one canonical ordering and miss whether order-irrelevant shuffling changes the answer, a baseline reliability property called for by emerging AI evaluation guidelines. We introduce Facet-Probe, a five-facet audit (option, evidence-chunk, document-rank, image-set, and mixed-modality ordering) of 18 frontier and open-weight MLLMs. A Bayesian item-response model separates ordering noise from per…
ゼロビズAX View — How Japanese companies can apply it
法務・金融・医療などで文書審査や判定にAIを用いる場合、証拠資料の提示順序で結論が変わる可能性が指摘される点に注意。現状、商用モデルでも完全には順序不変性が担保されていないため、同じ質問を複数順序で試すか、意思決定前に人間確認を組み込む運用が必須。オープンソースモデル導入時も同様に検証が必要。
