Amortized Inference for Gaussian Process Hyperparameters of Structured Kernels

1 code implementation16 Jun 2023 Matthias Bitzer, Mona Meister, Christoph Zimmer

We propose amortizing kernel parameter inference over a complete kernel-structure-family rather than a fixed kernel structure.

Hierarchical-Hyperplane Kernels for Actively Learning Gaussian Process Models of Nonstationary Systems

1 code implementation17 Mar 2023 Matthias Bitzer, Mona Meister, Christoph Zimmer

Machine learning methods that are used to produce the surrogate model should therefore address these problems by providing a scheme to keep the number of queries small, e. g. by using active learning and be able to capture the nonlinear and nonstationary properties of the system.

Structural Kernel Search via Bayesian Optimization and Symbolical Optimal Transport

1 code implementation21 Oct 2022 Matthias Bitzer, Mona Meister, Christoph Zimmer

Despite recent advances in automated machine learning, model selection is still a complex and computationally intensive process.

Spatial Decompositions for Large Scale SVMs

no code implementations1 Dec 2016 Philipp Thomann, Ingrid Blaschzyk, Mona Meister, Ingo Steinwart

Our contributions are two fold: On the theoretical side we establish an oracle inequality for the overall learning method using the hinge loss, and show that the resulting rates match those known for SVMs solving the complete optimization problem with Gaussian kernels.
