Fast Evaluation of Additive Kernels: Feature Arrangement, Fourier Methods, and Kernel Derivatives

1 code implementation26 Apr 2024 Theresa Wagner, Franziska Nestler, Martin Stoll

We here present a technique based on the non-equispaced fast Fourier transform (NFFT) with rigorous error analysis.

Gaussian Processes

Fast and interpretable Support Vector Classification based on the truncated ANOVA decomposition

no code implementations4 Feb 2024 Kseniya Akhalaya, Franziska Nestler, Daniel Potts

In small dimensional settings the Fast Fourier Transform (FFT) and related methods are a powerful tool in order to deal with the considered basis functions.

Learning in High-Dimensional Feature Spaces Using ANOVA-Based Fast Matrix-Vector Multiplication

1 code implementation19 Nov 2021 Franziska Nestler, Martin Stoll, Theresa Wagner

We propose the use of an ANOVA kernel, where we construct several kernels based on lower-dimensional feature spaces for which we provide fast algorithms realizing the matrix-vector products.
