Explainable AI For AI Robustness

What is Explainable AI for AI Robustness?

Explainable AI (XAI) refers to a set of methodologies and tools that make the decision-making processes of AI systems transparent and interpretable to humans. AI robustness, on the other hand, pertains to the ability of an AI system to perform reliably under diverse conditions, including adversarial scenarios, noisy data, and unexpected inputs. When combined, Explainable AI for AI robustness focuses on creating AI systems that are not only accurate but also resilient and understandable.

The goal of XAI is to bridge the gap between complex machine learning models and human comprehension. Traditional AI models, especially deep learning systems, often operate as "black boxes," where their internal workings are inscrutable. XAI techniques aim to demystify these processes, providing insights into how and why a model arrived at a particular decision. This transparency is crucial for ensuring that AI systems are robust, trustworthy, and aligned with ethical standards.
