Bayesian Vector AutoRegression with Factorised Granger-Causal Graphs

no code implementations6 Feb 2024 He Zhao, Vassili Kitsios, Terence J. O'Kane, Edwin V. Bonilla

We study the problem of automatically discovering Granger causal relations from observational multivariate time-series data. Vector autoregressive (VAR) models have been time-tested for this problem, including Bayesian variants and more recent developments using deep neural networks.

Free-Form Variational Inference for Gaussian Process State-Space Models

1 code implementation20 Feb 2023 Xuhui Fan, Edwin V. Bonilla, Terence J. O'Kane, Scott A. Sisson

However, inference in GPSSMs is computationally and statistically challenging due to the large number of latent variables in the model and the strong temporal dependencies between them.
