Researchers have introduced DynG-Diff, a novel diffusion-based framework designed for probabilistic multivariate time series forecasting. This framework addresses the challenge of "information heterogeneity" by employing a variable-sensitive dynamic guidance mechanism. DynG-Diff utilizes an unconditional diffusion backbone for modeling joint distributions and incorporates a state-aware policy network to adaptively adjust guidance strength based on variable reliability and noise levels. This approach allows for more precise forecasting by prioritizing high-confidence variables and mitigating interference from anomalous noise, demonstrating competitive performance against existing state-of-the-art methods.
