Latent Structure Modulation in Large Language Models Through Stochastic Concept Embedding Transitions (2502.05553v1)

Abstract: Stochastic embedding transitions introduce a probabilistic mechanism for adjusting token representations dynamically during inference, mitigating the constraints imposed through static or deterministic embeddings. A transition framework was proposed in which each token embedding evolved through probabilistic updates, ensuring adaptability while preserving semantic integrity across linguistic contexts. Empirical evaluations demonstrated that models incorporating stochastic transitions exhibited greater lexical diversity, improved generative coherence, and enhanced retention of low-frequency vocabulary, contributing to more varied sentence structures and reduced reliance on high-probability token selections. Statistical analyses of embedding drift across transformer layers indicated that representations evolved more flexibly without losing coherence, supporting the hypothesis that controlled stochasticity facilitated context-sensitive representation learning. Experimental results revealed that probabilistic embeddings introduced minor computational overhead while maintaining generative efficiency, reinforcing their feasibility in large-scale applications. A comparative study with traditional embedding approaches highlighted measurable gains in text completion accuracy, dialogue coherence, and structural complexity, confirming the effectiveness of stochastic transitions in enhancing representation expressiveness. Clustering patterns in the embedding space suggested that probabilistic updates preserved meaningful semantic groupings while enabling context-driven shifts, further validating the stability of the transition mechanism. Performance metrics indicated that stochastic transitions balanced adaptability and control, ensuring that generative outputs remained linguistically coherent without excessive randomness.
