Does Explainability Transfer? A Controlled Benchmark of Attribution Methods on Vision Transformers and CNNs

A controlled benchmark that evaluates attribution quality across five dimensions: faithfulness, localization, robustness, complexity, and computational cost shows that attribution performance is strongly architecture-dependent and that rankings established on CNNs do not reliably transfer to transformer-based models.

HiLRP: Toward One Trustworthy Explanation for Vision Transformer: Conservation-Valid Attribution via Attention Primitives

HiLRP alone preserves conservation across windowed, spatial-reduction, multi-axis, and linear-attention models, where naive extensions can produce zero or inflated relevance, and localizes attribution failures in class activation mapping.
