A Novel Adaptive Possibilistic Clustering Algorithm
Spyridoula D. Xenaki, Konstantinos D. Koutroumbas, Athanasios A. Rontogiannis
In this paper a novel possibilistic c-means clustering algorithm, called Adaptive Possibilistic c-means, is presented. Its main feature is that {\it all} its parameters, after thei…
Semisupervised hyperspectral image unmixing using a variational Bayes algorithm
Konstantinos E. Themelis, Athanasios A. Rontogiannis, Konstantinos D. Koutroumbas
This technical report presents a variational Bayes algorithm for semisupervised hyperspectral image unmixing. The presented Bayesian model employs a heavy tailed, nonnegatively tru…
Mobile Communication Systems in the Presence of Fading/Shadowing, Noise and Interference
Petros S. Bithas, Athanasios A. Rontogiannis
In this paper, the effects of interference on composite fading environments, where multipath fading coexists with shadowing, are investigated. Based on some mathematical convenient…
A variational Bayes framework for sparse adaptive estimation
Konstantinos E. Themelis, Athanasios A. Rontogiannis, Konstantinos D. Koutroumbas
Recently, a number of mostly -norm regularized least squares type deterministic algorithms have been proposed to address the problem of \emph{sparse} adaptive signal estima…
