Researchers have developed TimeID, a novel framework for source-free time series forecasting that leverages Large Language Models (LLMs) to adapt models to new datasets without direct access to the original source data. This approach addresses challenges posed by data scarcity and privacy regulations by employing dual-branch invariant disentangled feature learning and a parameter-free proxy denoising mechanism. The method also incorporates knowledge distillation to align predictions, demonstrating improved performance over existing methods with average reductions of 10.7% in MSE and 9.3% in MAE on real-world datasets.
