| Abstract: |
Deep-learning-based visual inspection is increasingly used in industrial quality control, yet high benchmark accuracy does not ensure that an individual decision is trustworthy. A detector may be confidently wrong, rely on misleading contextual cues, produce plausible but unfaithful explanations, or degrade when materials, sensors, illumination, or defect distributions change. Explainable AI (XAI) is therefore central to this doctoral research, not merely as a visualization layer but as a source of measurable evidence for diagnosing what drives predictions, where model reliance is misplaced, and when confidence may be misleading. The research develops an evidence-centered framework that connects XAI with predictive calibration, uncertainty, robustness, and human oversight at the level of individual detections. A preliminary steel-defect study motivates this direction by showing that localization and faithfulness provide different assessments of explanation quality across defect morphologies. Building on this foundation, the doctoral programme will examine how predictive and explanatory evidence interact, how they change under perturbation and distribution shift, and whether their combination can reveal unreliable detections beyond confidence alone. Diagnosed failures will further support actionable XAI for model adaptation, selective human-in-the-loop action, and evidence-grounded visual and natural-language explanations that communicate model evidence and limitations. The expected outcome is a lifecycle framework for explainable, trustworthy, adaptive, and human-centered industrial visual inspection. |
