Abstract
The increasing complexity of machine learning models has created a critical need for explainable artificial intelligence (XAI). While prominent post-hoc explanation frameworks like LIME and SHAP have provided foundational tools for model-agnostic interpretation, they often produce atomic feature-attribution scores that lack contextual realism and fail to provide holistic, actionable narratives. This paper introduces Hermai, a novel open-source Python framework designed to bridge this gap. Hermai is founded on the philosophical principles of hermeneutics, positing that true understanding arises from a dialogue between the parts (local predictions) and the whole (global model behavior). The framework makes three primary contributions: (1) a context-aware perturbation engine that generates plausible data points by respecting feature correlations, moving beyond the feature independence assumption of simpler methods; (2) a dual-mode explanatory system that generates both local, counterfactual-driven narratives for single predictions and general, rule-based explanations of the model's overall logic using surrogate models; and (3) the synthesis of these elements into human-readable, narrative explanations. We demonstrate Hermai's architecture, its practical application on a classic dataset, and argue that its hermeneutic approach offers a more intuitive, coherent, and trustworthy method for interpreting complex models.
