Testing Neural Networks via Bayesian-Guided Exploration of Decision Landscapes

arXiv:2606.04314v1 Announce Type: new Abstract: As neural networks are increasingly deployed in safety-critical domains, testing is essential to evaluate and improve their reliability. Existing testing methods, whether black-box or white-box, primarily use global mutation or coverage-guided strategies, both of which struggle to efficiently uncover diverse model failures while remaining proximate to the original data distribution and semantics. We propose BayesWarp, a testing framework that addresses this limitation by mutating decision-critical input regions identified via interpretable salien

Why this matters
Why now

As AI models advance rapidly, particularly in safety-critical applications, the need for robust and efficient testing methodologies becomes paramount to prevent failures and ensure reliability.

Why it’s important

This development proposes a new method to more effectively identify neural network vulnerabilities, which is crucial for the safe and ethical deployment of AI in sensitive domains, and directly impacts trust in AI systems.

What changes

The approach shifts from broad, less efficient testing to a more targeted, Bayesian-guided exploration of 'decision landscapes,' potentially leading to more reliable AI and accelerated deployment in regulated industries.
