MG-TSD: Multi-Granularity Time Series Diffusion Models with Guided Learning Process
However, the effective utilization of their strong modeling ability in the probabilistic time series forecasting task remains an open question, partially due to the challenge of instability arising from their stochastic nature.
MG-TSD: Multi-Granularity Time Series Diffusion Models with Guided Learning Process Download PDF
To address this challenge, we introduce a novel Multi-Granularity Time Series Diffusion (MG-TSD) model, which achieves state-of-the-art predictive performance by leveraging the inherent granularity levels within the data as given targets at intermediate diffusion steps to guide the learning process of diffusion models.
