wccsom (version 1.2.11)

SOM Networks for Comparing Patterns with Peak Shifts

Description

SOMs can be useful tools to group patterns containing several peaks. If peaks do not always occur at exactly the same position, classical distance measures cannot be used. This package provides SOM technology using the weighted crosscorrelation (WCC) distance.
