Fuzz testing is a technique traditionally used in software testing that provides invalid, unexpected, or random data to programs to identify potential software bugs and vulnerabilities. This method is now being adapted for machine learning (ML) systems to uncover robustness issues during development. Fuzz testing is particularly useful for computer vision applications due to their expansive input space and potential for subtle bugs. It helps identify problematic inputs by generating synthetic data that the system may not have encountered during training, thus improving system reliability. Techniques like DLFuzz and DeepHunter mutate input images to trigger failures by activating rarely used neurons or preserving image labels through transformations. Fuzz testing aids in stress testing ML systems, ensuring they perform well under expected conditions and fail gracefully when presented with challenging inputs. This approach can highlight areas where further data augmentation or collection is needed, and it is recommended as part of a comprehensive testing suite for ML components to enhance resilience against unexpected scenarios.
