SaSDim:Self-Adaptive Noise Scaling Diffusion Model for Spatial Time Series Imputation
IJCAI 2024poster
Spatial time series imputation is of great importance to various real-world applications. As the state-of-the-art generative models, diffusion models (e.g. CSDI) have outperformed statistical and autoregressive based models in time series imputation. However, diffusion models may introduce unstable…
