In the current artificial intelligence ecosystem, the ability to interpret and justify the decisions of classification models has become a strategic necessity for companies. The proliferation of approaches —from contrastive to abductive explanations, including those based on features or distances— has generated fragmentation that hinders their practical adoption. Faced with this challenge, the scientific community has proposed declarative query languages that allow specifying, combining, and analyzing these notions in a unified manner. ExplAIner represents a significant advance in this direction: a language that overcomes the limitations of previous proposals such as FOIL, which was unable to express queries based on optimality and had complexity issues that made it impractical even on decision trees. ExplAIner, on the other hand, covers a broad family of explanations —abductive, contrastive, attribute-based, and distance-based— and demonstrates that the evaluation of any query belongs to the Boolean hierarchy over Boolean models whose basic predicates are tractable in polynomial time. This has a direct algorithmic consequence: a fixed query can be evaluated with a constant number of calls to a SAT solver, while explanations seeking minimality according to strict partial orders require a polynomial number of such calls. This property is especially relevant in the field of formal XAI, where SAT solvers have become key tools for computing explanations in various classes of machine learning models.
From a business perspective, the adoption of languages like ExplAIner opens the door to more transparent and auditable artificial intelligence systems. At Q2BSTUDIO, we develop artificial intelligence services that integrate these principles, allowing organizations not only to build predictive models but also to understand their decisions through structured queries. Our experience in custom applications and custom software enables us to adapt these capabilities to complex production environments, combining them with AWS and Azure cloud services to ensure scalability and availability. Furthermore, cybersecurity is a fundamental pillar: when deploying AI agents or business intelligence solutions such as Power BI, we ensure that explanation mechanisms do not introduce vulnerabilities. The ability to generate minimal explanations through optimized calls to SAT solvers fits perfectly with the needs of AI for companies that require fast and justifiable responses in real time.
The declarative approach of ExplAIner also enhances the creation of AI agents that can reason about their own decisions. Instead of relying on black boxes, these agents can answer questions like 'Why was this case classified as positive?' or 'What minimal change in features would alter the classification?' using the same formalism. This is especially valuable in regulated sectors such as finance or healthcare, where traceability is mandatory. At Q2BSTUDIO, we combine these techniques with our process automation capabilities and business intelligence services to offer complete solutions ranging from data ingestion to interactive explanation of results. Integration with Power BI, for example, allows explanations to be visualized in executive dashboards, facilitating informed decision-making.
Ultimately, ExplAIner is not only an academic advance but also a conceptual tool that paves the way toward more responsible and accessible artificial intelligence. Companies wishing to leverage this potential can count on Q2BSTUDIO to implement explainability architectures based on declarative languages, backed by a solid foundation of custom applications, cybersecurity, and AWS and Azure cloud services. The convergence between theory and practice has never been so promising.
