Edge Preserving Image Denoising in Reproducing Kernel Hilbert Spaces
Pantelis Bouboulis, Sergios Theodoridis
The goal of this paper is the development of a novel approach for the problem of Noise Removal, based on the theory of Reproducing Kernels Hilbert Spaces (RKHS). The problem is cas…
Extension of Wirtinger Calculus in RKH Spaces and the Complex Kernel LMS
Pantelis Bouboulis, Sergios Theodoridis
Over the last decade, kernel methods for nonlinear processing have successfully been used in the machine learning community. However, so far, the emphasis has been on batch techniq…
The Complex Gaussian Kernel LMS algorithm
Pantelis Bouboulis, Sergios Theodoridis
Although the real reproducing kernels are used in an increasing number of machine learning problems, complex kernels have not, yet, been used, in spite of their potential interest…
Online Sparse System Identification and Signal Reconstruction using Projections onto Weighted Balls
Yannis Kopsinis, Konstantinos Slavakis, Sergios Theodoridis
This paper presents a novel projection-based adaptive algorithm for sparse signal and system identification. The sequentially observed data are used to generate an equivalent seque…
