Towards a standard methodology to evaluate internal cluster validity indices
(Elsevier, 2011-02-01)
The evaluation and comparison of internal cluster validity indices is a critical problem in the clustering area. The methodology used in most of the evaluations assumes that the clustering algorithms work correctly. We ...
Biologically-inspired data decorrelation for hyper-spectral imaging
(Springer, 2011)
Hyper-spectral data allows the construction of more robust statistical models to sample the material properties than the standard tri-chromatic color representation. However, because of the large dimensionality and complexity ...
