Explainable AI For AI Verification Standards

What is Explainable AI?

Explainable AI (XAI) refers to the subset of artificial intelligence focused on making AI systems interpretable and understandable to humans. Unlike traditional AI models, which often operate as "black boxes," XAI aims to provide clear, human-readable explanations for how decisions are made. This transparency is crucial for verifying the accuracy, fairness, and reliability of AI systems, especially in high-stakes domains like healthcare, finance, and autonomous vehicles.

XAI encompasses techniques such as feature attribution, rule-based models, and visualization tools that help stakeholders—developers, users, and regulators—understand the inner workings of AI algorithms. By bridging the gap between complex machine learning models and human comprehension, XAI ensures that AI systems align with ethical standards and regulatory requirements.
