The approach aims to provide structured, interpretable assessments to help clinicians critically evaluate ML predictions.", "body_md": "arXiv:2607.09664v1 Announce Type: new\nAbstract: To provide a structured and interpretable assessment, we decompose the image-based diagnosis into components following the Toulmin model of argumentation. This model consists of a claim, grounds, warrant, qualifier, rebuttal, and backing. Consider a claim generated by a machine learning (ML) model for retinal diagnosis. Rather than accepting this claim at face value, one could either apply explainable AI (XAI) methods or adopt an argumentation-based approach. In our framework, a model specialized in biomarker extraction from images provides the grounds. The warrant-linking the grounds to the claim - is analyzed by an agent equipped with medical knowledge; in our architecture, this role is fulfilled by a MedGemma agent. The qualifier is determined based on the overall quantitative evaluation of both the warrant and grounds models. Finally, a rebuttal is constructed using image similarity measures computed with MedSigLip. All these components are presented to the human expert, enabling a more informed and critical assessment of the ML-generated diagnosis.", "url": "https://wpnews.pro/news/from-ml-predictions-to-informed-diagnostic-assistance-using-the-toulmin-model-of", "canonical_source": "https://arxiv.org/abs/2607.09664", "published_at": "2026-07-14 04:00:00+00:00", "updated_at": "2026-07-14 04:23:24.052758+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "ai-research", "ai-ethics"], "entities": ["MedGemma", "MedSigLip", "Toulmin model"], "alternates": {"html": "https://wpnews.pro/news/from-ml-predictions-to-informed-diagnostic-assistance-using-the-toulmin-model-of", "markdown": "https://wpnews.pro/news/from-ml-predictions-to-informed-diagnostic-assistance-using-the-toulmin-model-of.md", "text": "https://wpnews.pro/news/from-ml-predictions-to-informed-diagnostic-assistance-using-the-toulmin-model-of.txt", "jsonld": "https://wpnews.pro/news/from-ml-predictions-to-informed-diagnostic-assistance-using-the-toulmin-model-of.jsonld"}}
