Is your AI Model Accurate Enough? The Difficult Choices Behind Rigorous AI Development and the EU AI Act

arXiv:2604.03254v1 Announce Type: cross Abstract: Technical and legal debates frequently suggest that "accuracy" is an objective, measurable, and purely technical property. We challenge this view, showing that evaluating AI performance fundamentally depends on context-dependent normative decisions. These techno-normative choices are crucial for rigorous AI deployment, as they determine which errors are prioritised, how risks are distributed, and how trade-offs between competing objectives are re
