SeFaR: Semantic Feature-aware Robustness Testing of Deep Neural Networks

Aug 10, 2026

This work addresses the insufficient robustness of deep neural networks in safety-critical scenarios caused by rare semantic shifts and the difficulty of verifying high-level semantic requirements. To tackle these challenges, the authors propose SeFaR, a framework that integrates diffusion models with vision-language models to generate realistic, semantically consistent, and diverse perturbations guided by natural language specifications and valid inputs. SeFaR employs a hierarchical concept model to systematically explore the feature space, incorporates domain knowledge through user-defined concepts, and leverages a feedback mechanism to identify requirement-irrelevant features that influence model decisions. This enables the generation of interpretable failure-inducing semantic concepts along with corresponding test samples. Experimental results demonstrate that SeFaR effectively uncovers model failures and accurately attributes them to specific semantic factors.
