Researchers have developed CoSPOT, a new framework for online time series forecasting that utilizes a pre-trained Large Language Model (LLM) as its core. This approach addresses limitations in existing methods that struggle with long-term adaptation and generalization to new patterns. CoSPOT achieves efficient online adaptation by keeping the LLM frozen and employing compositional spectral prompts, which are based on frequency-domain principles. These prompts guide the model using the input's overall distribution, significantly reducing the number of updated parameters during the online phase. Experiments show CoSPOT outperforms existing methods on real-world datasets, particularly in challenging online scenarios with distribution shifts. AI
