ANN-based Sensitivity Analysis

ANN-based Sensitivity Analysis is a technique using Artificial Neural Networks to quantify the impact of input variations on model outputs. Unlike traditional linear sensitivity methods, ANN-based approaches can capture non-linear and high-dimensional interactions, making them suitable for complex systems like autonomous vehicle AI. This method is critical for AI robustness assessment, as required by ISO 21434 and AI-specific risk management frameworks. It allows engineers to identify which input features most significantly affect AI decision-making, enabling targeted improvements to ensure system reliability and safety in diverse operating conditions.

In practice, the application follows three steps: First, a baseline AI model is established using historical and simulated driving data. Second, systematic perturbations are applied to input features—such as sensor noise or lighting conditions—to calculate sensitivity indices, quantifying each feature's impact on AI output. Third, the AI model is refined or fortified based on these sensitivity rankings to mitigate high-risk scenarios. For instance, a Taiwanese Tier 1 supplier reduced AI perception error rates by 25% in adverse weather conditions after implementing this methodology, demonstrating a clear improvement in AI system reliability and compliance with UNECE WP.29 regulations.

Taiwan enterprises typically face three challenges: data-scarcity, technical talent shortages, and evolving regulatory landscapes. To overcome data-scarcity, companies should adopt synthetic data generation and cloud-based AI platforms. Talent shortages can be addressed through partnerships with universities and upskilling existing engineering teams. Finally, to navigate the evolving AI regulations like ISO 42001, enterprises should adopt a phased approach—starting with critical AI functions like ADAS before expanding to full-scale AI governance. This ensures a measurable ROI and-90 day implementation roadmap, as practiced by Winners Consulting Services Co., Ltd. in numerous successful deployments.
