December 2017: A scikit-learn compatible collection of Python code for LVQ variants
including GMLVQ is avalailable now (thanks to our colleagues at CITEC, Bielefeld University!)
direct download (zip)

March 3, 2017: Matthias Gay defended his PhD thesis
Sparsity and random projections in time-frequency-based communication systems:
Theory and algorithm design for the OFDM physical layer

Congratulations, Dr. Gay!

January 2017: GMLVQ demo code (version 2.3) available
A slightly revised (minor bug fixed) collection of GMLVQ demo code in Matlab (TM) is available for
Generalized Matrix Relevance LVQ (GMLVQ), see here.
Also note that a more complete and more sophisticated Matlab (TM) implementation of GMLVQ and its variants is available here.

Many "services" provide unauthorized and incorrect research or publication profiles. I occasionally check the ones listed in the menu bar (left), but for (almost) complete lists of my publications, citation analyses, frequently cited papers etc. I strongly recommend my Scholar Google profile or the Web-of-Science based Researcher ID:

Research topics:         (see publications for details)

Theory, algorithm development, and applications of machine learning
· computational intelligence, supervised learning (classification, regression), unsupervised learning (e.g. clustering)
· machine learning in, e.g., medical data analysis, tumor classification, bioinformatics, astronomy
· non-standard distance measures, adaptive metrics in supervised learning, feature selection and relevance learning
· low-dimensional representation and discriminative visualization of labeled data sets
· mathematical analysis, design and optimization of training algorithms in artificial intelligence

An overview of my earlier contributions to the field of machine learning

Scientific Computing, Modelling and Simulation
· equilibrium and off-equilibrium Kinetic Monte Carlo (KMC) simulations
· theory and modelling of crystal growth, thin films and surfaces
· off-lattice simulation of hetero-epitaxial growth:   Stranski-Krastanov growth, misfit dislocations, self-organized nano-structures, surface alloys
