This transparency is especially crucial in applications like medical diagnosis, where the ability to explain a diagnosis is vital for acceptance and trust in AI systems.
One widely used XAI technique is Local Interpretable Model-agnostic Explanations (LIME). LIME approximates a black-box model’s behavior by fitting a simple interpretable model in the vicinity of a particular instance to explain the model’s prediction for that instance. The simplicity of the local model allows human users to understand the factors that influenced the model’s decision.
Another popular XAI technique is SHAP, which derives from cooperative game theory’s concept of Shapley values. SHAP provides a uniform framework for defining the output of any machine learning approach based on the contributions of each feature to the prediction. This technique offers global and local explanations, comprehensively understanding model behavior across different instances and features.
Developers can build more trustworthy and accountable AI systems by integrating XAI techniques into machine learning models. Explainable AI also plays a crucial role in meeting regulatory requirements, such as GDPR (General Data Protection Regulation), which mandates that users have the right to know the logic behind automated decisions that impact them.
