arXiv:2605.23402v1 Announce Type: new Abstract: Effectively modeling non-stationary dynamics in probabilistic multivariate time series(MTS) forecasting requires balancing expressiveness with robustness. Existing parametric approaches benefit from strong inductive biases but lack flexibility, whereas deep generative models struggle to capture complex temporal dependencies without extensive data and computation. We introduce Parametric Prior Mapping (PPM), a framework that injects parametric structural priors into a generative modeling process. Specifically, PPM utilizes a parametric estimator t
This research addresses a long-standing challenge in time series forecasting, particularly relevant given the increasing complexity and non-stationarity of real-world data in computational and AI applications.
Improved probabilistic time series forecasting can lead to more robust and accurate predictions across various domains, from financial markets to climate modeling and demand forecasting, enhancing decision-making capabilities.
The introduction of the Parametric Prior Mapping (PPM) framework offers a new method to combine the strengths of parametric inductive biases with the flexibility of deep generative models, potentially improving forecasting accuracy and efficiency in non-stationary environments.
