While there have been major improvements in the field of AI in the last decade, there are also major issues that AI is still having trouble resolving such as transparency and explainability. Since the inception of AI, deep learning has been a dominant approach for many applications.
While there have been significant improvements in the approach, many consider it as approach in that the reasoning behind many of the conclusions and predictions is pretty much unverifiable. Relating to the previously mentioned issue, the more the AI field is utilized in high stake sectors such as healthcare and finance, the more evident the need for transparency in decision making is. One of the leading approaches in addressing the above issues in explainable AI is Neural-Symbolic AI, an integration of deep learning and symbolic reasoning (Zhang & Sheng, 2024).
Neural-Symbolic AI is the integration of neural network and symbolic reasoning, the two foundation approaches to intelligence. Neural networks are specially tuned for perception, classification, and predictive analytics. This offers Neural networks an edge in analyzing unstructured and complex datasets as they perform operations in a predictive and illustrative way. On the other hand, symbolic reasoning, as the name suggests, is more about applying logic and rules to solve a problem. The more structured approach of symbolic reasoning offers an edge in decision making as it can be consistent as the underlying rules are unchanging (d’Avila Garcez & Lamb, 2023). The integration of the two approaches offers the potential of AI systems that learn from the data as well as offer reasoning with structured knowledge, thus having the necessary qualities of transparency and interpretability.
There have been huge advancements in Neural-Symbolic AI and the reason for the increased focus and interest in this field. One of the advancements includes the focus of international regulatory authorities on responsible and explainable Artificial Intelligence. Legislations such as the EU AI Act and the GCC Digital Governance Frameworks place policy obligations to explain and justify the workings of the model in question — something purely neural system models do not present (European Commission, 2024). The competencies and the problems of generative AI pose the other reason as it exemplifies. Knowledge-grounded systems are necessary because generative AI presents hallucinations. Neural-symbolic models are, in fact, the solution to hallucinations because such models contain rule-based systems to ensure consistency (Yannam et al., 2025). The other reason includes the need for AI systems that can act predictably in the face of uncertainty — this demand is especially prevalent in high-stakes systems such as healthcare, autonomous driving, and cybersecurity (Zhang & Sheng, 2024).
There are still challenges to be dealt with. While Neural-Symbolic AI is very promising, the integration of symbolic reasoning into large neural systems is pedagogically difficult, and there are no standard benchmarks, which is why they are still in progress. (d’Avila Garcez & Lamb, 2023). Computational costs of systems that use large sets of symbolic rules can be high. Despite these challenges, there is still collaboration with R&D that is improving the situation.

Neural-Symbolic AI is very promising. The integration of Neural AI and Symbolic systems will allow us to create much more transparent and safer systems that integrate in a much more human-friendly way. The closing of these systems will generate new standards. As big industries and regulators start to be more open about responsible AI and adopt it, the technology that will be used for this in Neural-Symbolic AI will be the most advanced for Digital Transformation.
