Explainable AI In AI Reliability Testing

What is Explainable AI?

Explainable AI (XAI) refers to a set of techniques and methodologies designed to make AI systems more transparent and interpretable. Unlike traditional AI models, which often operate as "black boxes," XAI aims to provide human-understandable explanations for the decisions and predictions made by AI systems. This transparency is crucial for reliability testing, as it allows developers and stakeholders to identify potential biases, errors, or inconsistencies in the model's behavior.

Key components of XAI include:

• Interpretability: The ability to understand the inner workings of an AI model.
• Transparency: Clear insights into the decision-making process.
• Accountability: Ensuring that AI systems can be held responsible for their actions.
