XAI aims to increase transparency and accountability in AI systems by making their decision-making processes more explainable to humans. Interest in XAI grew as machine learning models became more complex and opaque. While techniques like deep learning are very effective, they can be difficult for humans to understand. This lack of explainability poses challenges for assessing accountability when things go wrong. Future work on XAI focuses on developing more interpretable and transparent models to provide insight into how AI systems derive their results.
