Beyond Accuracy: Introducing a Symbolic-Mechanistic Approach to Interpretable Evaluation

arXiv:2603.23517v1 Announce Type: new Abstract: Accuracy-based evaluation cannot reliably distinguish genuine generalization from shortcuts like memorization, leakage, or brittle heuristics, especially in small-data regimes. In this position paper, we argue for mechanism-aware evaluation that combines task-relevant symbolic rules with mechanistic interpretability, yielding algorithmic pass/fail scores that show exactly where models generalize versus exploit patterns. We demonstrate this on NL-to-SQL by training two identical architectures under different conditions: one without schema information (forcing memorization), one with schema (enabling grounding). Standard evaluation shows the memorization model achieves 94% field-name accuracy on unseen data, falsely suggesting competence. Our symbolic-mechanistic evaluation reveals this model violates core schema generalization rules, a failure invisible to accuracy metrics.

Executive Summary

This article introduces a novel approach to interpretable evaluation in machine learning, focusing on mechanism-aware assessment that combines symbolic rules with mechanistic interpretability. The authors argue that accuracy-based evaluation is insufficient for distinguishing genuine generalization from shallow learning strategies like memorization. The proposed symbolic-mechanistic approach is demonstrated on a natural language to SQL (NL-to-SQL) task, highlighting its ability to reveal model failures invisible to traditional accuracy metrics. The authors' findings have significant implications for model evaluation and development in AI, particularly in small-data regimes.
