Belief Filtering for Epistemic Control in Linguistic State Space

Sebastian Dumbrava

TL;DR

This work tackles the problem of regulating an AI system's internal cognitive states to achieve safer, more aligned behavior. It proposes the Semantic Manifold, a linguistically grounded architecture where beliefs are dynamic ensembles $\phi = \{\varphi_i\}$ of natural-language fragments, organized by abstraction level $k$ and semantic sectors $\Sigma$. The core contribution is belief filtering, a content-aware mechanism that selectively admits or excludes fragments based on semantic content, enabling targeted control across assimilation, retrieval, reflection, and planning. The framework emphasizes interpretability, modularity, and auditability, offering an architectural approach to epistemic safety by intervening directly in the agent's internal semantic space rather than only at the output level. This approach aims to advance AI safety and alignment by integrating regulatory capabilities into the cognitive substrate, with implications for design, evaluation, and governance of future AI systems.

Abstract

We examine belief filtering as a mechanism for the epistemic control of artificial agents, focusing on the regulation of internal cognitive states represented as linguistic expressions. This mechanism is developed within the Semantic Manifold framework, where belief states are dynamic, structured ensembles of natural language fragments. Belief filters act as content-aware operations on these fragments across various cognitive transitions. This paper illustrates how the inherent interpretability and modularity of such a linguistically-grounded cognitive architecture directly enable belief filtering, offering a principled approach to agent regulation. The study highlights the potential for enhancing AI safety and alignment through structured interventions in an agent's internal semantic space and points to new directions for architecturally embedded cognitive governance.
