In the rapidly growing world of Artificial Intelligence (AI), the need to make algorithmic decisions understandable and transparent has gained importance. As machine learning (ML) is increasingly applied in critical areas such as medicine, finance, and law, the lack of explainability in AI models presents one of the biggest challenges. The ability to make complex models comprehensible is crucial for user acceptance and trust.

Explainable Artificial Intelligence (XAI) aims to make models and their decisions understandable to humans. This is especially important when AI systems are deployed in sensitive or high-risk areas where incorrect decisions can have far-reaching consequences. To achieve this, researchers and practitioners have developed various methodologies that allow for deeper insights into how models function.

A key aspect of XAI is the distinction between intrinsically explainable models and methods that provide post-hoc explanations. Intrinsically explainable models are inherently transparent, such as decision trees or linear models, which are easy to understand due to their simple structure. On the other hand, there are complex yet powerful models like deep neural networks, which need to be equipped with special techniques to disclose their decision-making processes. This is where methods such as LIME (Local Interpretable Model-agnostic Explanations) and SHAP (SHapley Additive exPlanations) come into play, which are based on principles from game theory and enable the explanation of the impact of individual input data on model predictions.

In addition to these models and methods, visual approaches and techniques for visualizing learning processes are increasingly in demand. By visually representing data flows and weightings in models, the understanding and traceability of AI decisions can be improved. The continuous development of XAI is therefore not only a technical issue but also a societal concern, as it helps to build trust in AI systems and ensure their ethically responsible use.
