DeepHGNN: Study of Graph Neural Network based Forecasting Methods for Hierarchically Related Multivariate Time Series

no code implementations29 May 2024 Abishek Sriramulu, Nicolas Fourrier, Christoph Bergmeir

Graph Neural Networks (GNN) have gained significant traction in the forecasting domain, especially for their capacity to simultaneously account for intra-series temporal correlations and inter-series relationships.

Adaptive Dependency Learning Graph Neural Networks

1 code implementation6 Dec 2023 Abishek Sriramulu, Nicolas Fourrier, Christoph Bergmeir

In this paper, we propose a hybrid approach combining neural networks and statistical structure learning models to self-learn the dependencies and construct a dynamically changing dependency graph from multivariate data aiming to enable the use of GNNs for multivariate forecasting even when a well-defined graph does not exist.
