arXiv:2605.21041v1 Announce Type: cross Abstract: Gaussian processes (GPs) offer a principled probabilistic model over functions, but exact inference is restricted to the linear-Gaussian regime. We establish an explicit equivalence between GPs and a class of linear diffusion models, recasting predictive sampling as an ODE with closed-form Gaussian dynamics and a likelihood-dependent guidance term that admits a simple Monte Carlo approximation. In the linear-Gaussian setting, we recover standard GP conditioning exactly; beyond conjugacy, the same machinery handles any conditioning statement adm
This research provides a novel theoretical and practical advancement in Gaussian Processes, a foundational AI technique, expanding their applicability beyond traditional linear-Gaussian constraints.
Improving the conditioning of Gaussian Processes allows for more complex and robust probabilistic modeling in AI, leading to more accurate predictions and better handling of diverse data types.
The ability to condition Gaussian Processes on a wider variety of data types, including non-conjugate likelihoods, significantly enhances their flexibility and inferential power for AI practitioners.
