PDE-Residual-Informed Kriging

Read the original on arXiv Machine Learning →

The paper introduces PDE‑Residual‑Informed Kriging (PRIK), a Gaussian process framework that embeds global PDE residual information directly into its covariance structure via a PDE‑residual kernel. PRIK yields a posterior mean with minimal integrated squared PDE residual and offers statistical interpretations linking variance to residual energy. The authors prove quasi‑optimality and convergence rates, and demonstrate the method’s PDE‑solving capability through numerical experiments.

Scalable Logistic Gaussian Process Density Regression with Kinetic Langevin Sampling

The paper introduces a scalable Bayesian method for conditional density estimation using a logistic Gaussian process. It models the log conditional density with a separable covariance— a Matérn kernel on the response dimension and a Nyström-feature kernel on covariates— and samples the latent field via kinetic Langevin dynamics instead of traditional approximations. Experiments on photometric‑redshift data with up to 3.9 million observations show the approach matches state‑of‑the‑art tabular foundation models on density and calibration metrics.

Constrained Probabilistic Numerics: Gaussian Process Solvers for Linear PDEs under Linear Inequality Constraints

The paper introduces a method to incorporate linear inequality constraints—such as nonnegativity, monotonicity, and no‑arbitrage—into Gaussian process solvers for linear partial differential equations. By proving that conditioning a Gaussian process jointly on equality observations and a finite‑dimensional inequality event is equivalent to sequential conditioning, the authors obtain a non‑Gaussian but computable posterior that respects both PDE physics and inequality constraints. Experiments on Poisson problems, option‑price surfaces, and air‑quality data show substantial error reductions and improved adherence to constraints when the new method is applied.
