Explainable AI In AI Risk Standards

What is Explainable AI in AI Risk Standards?

Explainable AI (XAI) refers to AI systems designed to provide clear, understandable, and interpretable outputs to human users. Unlike traditional "black-box" AI models, which often operate without transparency, XAI aims to make the decision-making process of AI systems more accessible and comprehensible. In the context of AI risk standards, XAI ensures that AI systems adhere to ethical guidelines, regulatory requirements, and industry best practices. It bridges the gap between complex algorithms and human understanding, enabling stakeholders to trust and validate AI-driven decisions.

Key components of XAI in AI risk standards include:

• Transparency: The ability to explain how an AI system arrives at its decisions.
• Interpretability: Ensuring that the outputs of an AI system can be understood by non-technical users.
• Accountability: Assigning responsibility for AI decisions to specific individuals or teams.
• Fairness: Identifying and mitigating biases in AI models to ensure equitable outcomes.
