Explainable AI (XAI) comprises techniques for representing and assessing the decision basis of machine learning models. It enables stakeholders to understand model behavior, detect bias and meet regulatory requirements. XAI is particularly relevant in high-stakes domains such as healthcare, finance and public administration.

Explainable AI (XAI) covers methods and tools that make the decision foundations of machine-learning models transparent, understandable, and verifiable. It aims to support trust, compliance, and debugging for AI decisions.
Many ML models act as a “black box” in deployment: it is often unclear to people why the system produced a particular decision or action. XAI emerged as a research direction to make these decision bases transparent/interpret-able/explain-able, addressing safety and trust needs around automated decision-making. A concretely documented development path is the DARPA program “Explainable Artificial Intelligence (XAI)”: it targeted the inability of machine learning systems to explain decisions and actions to human users and addressed the performance-vs-explainability trade space (initial implementations: May 2018; Phase-1 evaluation: November 2018).
Think of XAI in three steps: (1) derive explanation-ready artifacts from model behavior (e.g., reasons/contributions for a specific prediction rather than raw outputs only). (2) deliver them through a human-usable explanation interface so people can apply them during judgment. (3) evaluate explanation quality against the concrete evaluation target—building trust, enabling users to challenge decisions, or supporting debugging hypotheses. Finally, document what the explanation covers and what it does not in real use.
In operation, the rationale behind model decisions is often not transparent to users.
XAI surfaces the information that decisions/predictions are based on.
From model behavior, representations are produced that humans can interpret and check (often instance-level reasons/contributions).
Explanations must be presented in a way that users can actually understand and use in their workflow.
What counts as a “good” explanation depends on the purpose (trust, challenge, debugging).
XAI is useful when AI decisions must be justified or operationally accountable to stakeholders—for example to assess risk, detect bias, or derive debugging hypotheses from observed model behavior. The key prerequisite is alignment between the chosen explanation method and the evaluation target, including adequate coverage. Trade-offs remain: added modeling/data/interface effort, possible tension between predictive performance and explainability, and the risk that explanations may be understandable yet insufficiently correct or incomplete.
