ScoreGrad: Multivariate Probabilistic Time Series Forecasting with Continuous Energy-based Generative Models

Yan, Tijin, Zhang, Hongwei, Zhou, Tong et al.

Understand

Multivariate time series prediction has attracted a lot of attention because of its wide applications such as intelligence transportation, AIOps.

  • Generative models have achieved impressive results in time series modeling because they can model data distribution and take noise into consideration.
  • However, many existing works can not be widely used because of the constraints of functional form of generative models or the sensitivity to hyperparameters.
  • In this paper, we propose ScoreGrad, a multivariate probabilistic time series forecasting framework based on continuous energy-based generative models.
