Transformed Latent Variable Multi-Output Gaussian Processes

ICML 2026poster

Multi-Output Gaussian Processes (MOGPs) provide a principled probabilistic framework for modelling correlated outputs but face scalability bottlenecks when applied to datasets with high-dimensional output spaces. To maintain tractability, existing methods typically resort to restrictive assumptions,…

Adaptive RKHS Fourier Features for Compositional Gaussian Process Models

AISTATS 2025poster

Deep Gaussian Processes (DGPs) leverage a compositional structure to model non-stationary processes. DGPs typically rely on local inducing point approximations across intermediate GP layers. Recent advances in DGP inference have shown that incorporating global Fourier features from the Reproducing K…

Neighbour-Driven Gaussian Process Variational Autoencoders for Scalable Structured Latent Modelling

ICML 2025poster

Gaussian Process (GP) Variational Autoencoders (VAEs) extend standard VAEs by replacing the fully factorised Gaussian prior with a GP prior, thereby capturing richer correlations among latent variables. However, performing exact GP inference in large-scale GPVAEs is computationally prohibitive, ofte…
