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…
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…
