scripts default iconClustering by Passing Messages (Scripts) Publisher's description

As recently published in Science (see reference)

As recently published in Science (see reference)

Simple and effective means of clustering any data for which a similarity matrix can be constructed. Does not require similarity matrix meet the standards for a metric. The algorithm applies in cases where the similarity matrix is not symmetric (the distance from point i to j can be different from j to i). And it does not require triangular equalities (e.g. the hypoteneus can be less than the sum of the other sides)

usage is very simple (given an m x m similarity matrix)

ex = affprop(s)

returns ex, a m x 1 vector of indices, such that ex(i) is the exemplar for the ith point.

see affyprop_demo for a complete example with simple 2d data. See reference for more complex examples including face matching.

System Requirements:

MATLAB 7.4 (R2007a)
