The Concept and Argumentation Model (CAM) is a novel framework designed for tabular data in high-risk domains, integrating human-understandable knowledge with data-driven insights. It constructs hierarchical argumentative structures, known as Quantitative Argumentation Frameworks (QAFs), from both raw data and its textual descriptions. This approach mirrors human cognitive processes by abstracting fine-grained features into higher-level concepts (e.g., grouping inquiry-related features into an 'Inquiry' concept). This concept tree structure allows CAM to generate decisions based on human-level knowledge, with its reasoning process being intrinsically interpretable. Unlike traditional black-box models, every neuron and its connections within CAM's underlying neural network find a corresponding, human-interpretable knowledge representation.
A core strength of CAM lies in its ability to provide transparent and interactive dialogical explanations. Leveraging its inherent argumentative structure, CAM can explain its decisions for any node (decision, concept, or feature) by identifying supporting and attacking arguments. The SSC algorithm simplifies these explanations by focusing on dominant arguments with significant impacts, ensuring the dialogue is both concise and consistent with CAM's original decision. These human-aligned explanations use natural language descriptions of features and concepts, making the model's internal reasoning comprehensible. For instance, in a credit risk assessment, CAM can explain why a case was high-risk by detailing how "Inquiry" factors contributed negatively, even if "ExternalRiskEstimation" was positive. This level of detail and human-centric reasoning fosters greater trust and understanding in AI-driven decisions.
CAM achieves a balance between high predictive accuracy and robustness, critical for enterprise applications. Data experiments on open-source benchmarks (Fico, Mimic3) and real-world business datasets (Alibaba e-commerce fraud detection) demonstrate competitive AUC scores compared to state-of-the-art interpretable and black-box models. Notably, CAM exhibits high stability across experiments, outperforming many other models in this regard, a direct benefit of its human-level knowledge grounding. Furthermore, CAM proves not sensitive to imbalanced data, maintaining consistent performance across various positive rates. The field-wise learning algorithm contributes to efficiency, significantly reducing modeling time for large datasets—for example, processing 1,000,000 instances in just 38 minutes with 16 parallel cores. This combination of accuracy, stability, and efficiency makes CAM a practical solution for high-stakes enterprise AI.

FICO Credit Risk Assessment: CAM's Interpretative Power
In a real-world FICO credit risk assessment, CAM successfully identified a case as 'high risk' (s(Risk) = 0.84). Through its simplified QAF and the SSC algorithm, CAM reduced the complexity to s(Risk) = 0.54, maintaining the same decision with improved interpretability. For instance, the model revealed that 'Inquiry' (multiple recent credit applications) had the largest positive influence on risk, outweighing a positive 'ExternalRiskEstimate'. This detail, such as the customer applying 9 times for new credit cards within 6 months, provided a crucial human-understandable rationale for the high-risk assessment, enhancing trust and actionability for bank experts.
