Explainable AI In AI Validation Standards

What is Explainable AI in AI Validation Standards?

Explainable AI (XAI) refers to the methodologies and techniques that make AI systems' decision-making processes transparent and interpretable to humans. In the context of AI validation standards, XAI ensures that AI models meet predefined criteria for accuracy, fairness, and reliability while providing clear explanations for their outputs. This is particularly important in high-stakes industries like healthcare, finance, and autonomous systems, where understanding the "why" behind an AI decision can be as crucial as the decision itself.

XAI in AI validation standards involves a combination of technical and ethical considerations. It ensures that AI systems are not only performing as expected but are also free from biases, compliant with regulations, and aligned with organizational goals. By making AI systems explainable, stakeholders can trust and adopt these technologies with greater confidence.
