DenseSwinLight: A Hybrid CNN–Transformer Model with Lightweight Post-hoc Fusion for Visual Explainability

The Hybrid CNN–Transformer architectures offer high-performance image analysis by combining local extraction and global contextual modeling. However, this integration complicates decision-making mechanisms and increases the opacity of models, making them difficult for human users to interpret. We propose DenseSwinLight...

A Formal Methodological Framework for Auditing Robustness and Fidelity in Explainable AI: From Application to Trust Certification

An auditing protocol is constructed that measures two properties of any post-hoc explainer: robustness (how stable the explanation is under input perturbation) and fidelity (whether the features deemed important actually drive the model's prediction).
