Explainable AI: Applications, Challenges, Current Solutions and Future Research Directions

The fast integration of artificial intelligence (AI) into essential domains such as healthcare, finance, and the operation of autonomous systems has come to bear significant challenges related to transparency, trust, and accountability. The more complex the AI models and deep learning frameworks are, the more pressing the necessity of Explainable AI (XAI) becomes. This paper surveys the state of the art in XAI, addressing not only the benefits that such applications bring but also discussing the challenges inherently met in the practice of XAI. Although such transparency techniques are crucial for fostering user trust and the ethical deployment of AI systems, the field is relatively young and has several serious roadblocks. These include a widespread debate on the interpretability-performance trade-off, deficiencies in evaluation metrics, and limitations in terms of scalability. It also focuses on current research efforts to overcome challenges and develop better, more robust, context-aware XAI techniques. These requirements will be central in the future of artificial intelligence, in which the demands for transparency and interpretability are bound to increase with the rise in the embedding of artificial intelligence in society. This study highlights the importance of ongoing research into XAI to ensure that AI developments are influential but also responsible and trustworthy.
