Clustering

This class contains SpectraClustering classes These classes are components for clustering all kinds of data for which a distance relation, normalizable in the range of [0,1], is available. Mainly this will be data for which there is a corresponding CompareFunctor given (e.g. PeakSpectrum) that is yielding the similarity normalized in the range of [0,1] of such two elements, so it can easily converted to the needed distances.

clustering function for binned PeakSpectrum

A version of the clustering function for PeakSpectra employing binned similarity methods. From the given PeakSpectrum BinnedSpectrum are generated, so the similarity functor

BinnedSpectrumCompareFunctor can be applied.

Parameters

data	vector of PeakSpectrum s to be clustered
comparator	a BinnedSpectrumCompareFunctor
sz	the desired binsize for the BinnedSpectrum s
sp	the desired binspread for the BinnedSpectrum s
offset	the desired bins offset for the BinnedSpectrum s
clusterer	a clustermethod implementation, base class ClusterFunctor
cluster_tree	the vector that will hold the BinaryTreeNodes representing the clustering (for further investigation with the ClusterAnalyzer methods)
original_distance	the DistanceMatrix holding the pairwise distances of the elements in data, will be made newly if given size does not fit to the number of elements given in data
