The Contrastive Credence Constraint for Large Language Models: A Mathematical Governor for Epistemic Calibration

Description

This paper formalizes the LLM Contrastive Credence Constraint (LLM-CCC), a unified mathematical framework designed to regulate algorithmic overreach and mitigate hallucinations in Large Language Models (LLMs).  

The research addresses the critical epistemic gap where generative models frequently output sequences with high algorithmic confidence (P \rightarrow 1) despite lacking proportional grounding in empirical evidence or training data consensus. By mapping a model's maximum permissible confidence as a contrastive function of contextual grounding against the epistemic uncertainty of Out-of-Distribution (OOD) alternatives and adversarial edge cases (U_{OOD}), this study establishes a strict normative ceiling for generative belief.  

Key contributions include:

The LLM-CCC Inequality: A universal mathematical governor that bounds operational certainty based on the sequence's net contextual grounding, penalized by a multiplicative generative complexity coefficient (S_{gen}) for unverified inferential leaps.  

The Hallucination Index (V_{LLM}): A formal diagnostic metric that quantifies the variance between an agent's declared softmax confidence and its maximum mathematically justified credence, providing a clear safety gate for alignment engineering.  

Principle of Task-Dependent Parity: An architectural guideline to ensure that the competitive alternative space used for contrastive grounding matches the specific utility and structural criteria of the model's operational task.  

This framework moves beyond post-hoc calibration adjustments, shifting the engineering standard toward radical epistemic calibration, where an artificial system's internal operational certainty must strictly mirror the mathematical margins of its comparative data-grounded justification. This research is foundational for AI safety architectures seeking to enforce strict intellectual transparency in automated decision-making engines.
