Detailed Description

template<class TListSample, class TMap, class TSOMLearningBehaviorFunctor = Functor::CzihoSOMLearningBehaviorFunctor, class TSOMNeighborhoodBehaviorFunctor = Functor::CzihoSOMNeighborhoodBehaviorFunctor>
class otb::PeriodicSOM< TListSample, TMap, TSOMLearningBehaviorFunctor, TSOMNeighborhoodBehaviorFunctor >

This class is responsible for the learning of a self organizing map when considered as a torus.

This class extends the SOM object which implements the Self Organizing Map (or Kohonen map) learning.

The learning process iteratively select the best-response neuron for each input vector, enhancing its response and the response of its neighbors with respect to a certain radius, computed from an initial radius, and to a certain learning factor, decreasing at each iteration.

The behavior of the neighborhood is given by a functor (templated) which parameter is the current iteration. It returns a neighborhood of type

SizeType

.

The behavior of the learning factor (hold by a beta variable) is given by an other functor which parameter is the current iteration. It returns a beta value of type

double

.

The SOMMap produced as output can be either initialized with a constant custom value or randomly generated following a normal law. The seed for the random initialization can be modified.
