Detailed Description

Neighborhood size behavior over SOM training phase.

This class implements an evolution of the neighborhood size over the SOM training. It is issued from A. Cziho's PhD: "Compression d'images et analyse de contenu par quantification vectorielle" PhD dissertation, University of Rennes I, Rennes, France. May 5th, 1999.

The behavior of the radius r (ie.

component 0, 1, ...) is given by: $ r = r_{\textrm{init}} \left( 1 - \frac{t}{t_{\textrm{end}}} \right)^2 $

CzihoSOMNeighborhoodBehaviorFunctor uses some parameters of the SOM class such as:




which are parameters of the functor function.


is templated with the dimension of the neighborhoodSize.
