STELLA: Guiding Large Language Models for Time Series Forecasting with Semantic Abstractions

arXiv — cs.CLFriday, December 5, 2025 at 5:00:00 AM
  • The introduction of STELLA (Semantic-Temporal Alignment with Language Abstractions) aims to enhance the effectiveness of Large Language Models (LLMs) in time series forecasting by incorporating structured supplementary information. This framework addresses the limitations of existing prompting strategies that rely on static correlations, thereby improving the reasoning capabilities of LLMs through a dynamic semantic abstraction mechanism that separates input series into trend, seasonality, and residual components.
  • This development is significant as it allows for a more nuanced understanding of time series data, which is crucial for various applications in finance, meteorology, and other fields that rely on accurate forecasting. By utilizing Hierarchical Semantic Anchors, STELLA enhances both global and instance-specific context, potentially leading to better predictive performance and decision-making processes.
  • The advancement of STELLA reflects a broader trend in AI research focused on improving the interpretability and generalization of LLMs across diverse domains. This includes recent methodologies like generative caching and test-time steering vectors, which aim to optimize LLM outputs and enhance their contextual understanding. As the field evolves, the integration of episodic memory and retrieval-augmented generation frameworks further emphasizes the importance of contextual awareness in AI, highlighting ongoing efforts to refine LLM capabilities.
