Kernel-Based Methods

'This is an extremely helpful book for researchers who work with kernels in the context of modern applications – including machine learning, image processing, and data science. It provides important new theoretical results as well as numerous practical examples, and supplies the necessary software to open up new kernel-based fields of research.' Robert Schaback, University of Göttingen
'This volume complements the existing textbooks on kernel methods with exciting new topics such as rational kernel approximation, approximation of discontinuous data, and learning with kernels.' Elisabeth Larsson, Uppsala University
'Kernel and radial basis function-based approximations are at the very centre of modern multivariate approximation theory and applications. This book reviews state-of-the-art approaches including excellent summaries of the basic theoretical results on kernel-based methods and their applications; the practical aspects of these tools are particularly emphasized and a great number of very useful tools, including software, is included. This is a book that should be in every application-interested scientist who works with multivariate approximations.' Martin Buhmann, University of Giessen
'This monograph complements existing books on kernels and their applications by focusing on promising recent developments – such as rational kernels, data-driven kernels, variably scaled kernels, persistence kernels – the details of which were previously accessible only in original research publications.' Oleg Davydov, University of Giessen
'This book seamlessly bridges rigorous mathematical theory with practical, hands-on applications. Readers will explore cutting-edge solutions for scattered data problems – with a special focus on variably scaled kernels (VSKs) – alongside imaging challenges and vital machine learning tools like support vector machines (SVMs). To ensure immediate implementation, the text introduces key software packages with direct links to open-source code repositories on GitHub. Designed for students, applied scientists, and practitioners alike, this text bypasses advanced functional analysis to deliver a direct, comprehensive understanding of kernel-based algorithms.'
