Constructor & Destructor Documentation

PndMvaSomTrainer()

PndMvaSomTrainer::PndMvaSomTrainer ( DataPoints const *const  InputData, size_t  mapWidth, size_t  mapHeight, size_t  numIter, MapNodeInitType  initType = SOM_RAND_FROM_DATA, GridInitType  gridInitType = RECTANGULAR  )

explicit

Constructor.

Parameters

InputData	Input Data points.
mapWidth	The width of the SOM.
mapHeight	The height of the SOM.
numIter	Number of learning iterations.
initType	The scheme to initialize weight of each node.

~PndMvaSomTrainer()

virtual PndMvaSomTrainer::~PndMvaSomTrainer ( )

virtual

Destructor.

Member Function Documentation

Calibrate()

virtual void PndMvaSomTrainer::Calibrate ( )

virtual

Calibrate the map (post labeling). The current implementation uses the winner takes all scheme. The label with the largest count determines the node label. Note that also a list of all labels is kept in de node itself.

GetInputDataSet()

DataPoints const & PndMvaSomTrainer::GetInputDataSet ( ) const

inline

Get the input data set.

Returns

The list of input data points.

Definition at line 220 of file PndMvaSOMTrainer.h.

{
  return (*(this->m_DataSet));
};

GetLambda()

double PndMvaSomTrainer::GetLambda ( ) const

inline

Definition at line 245 of file PndMvaSOMTrainer.h.

{
  return this->m_lambda;
};

GetMapHeight()

size_t PndMvaSomTrainer::GetMapHeight ( ) const

inline

Map size.

{
  return this->m_MapHeight;
};

GetMapWidth()

size_t PndMvaSomTrainer::GetMapWidth ( ) const

inline

Definition at line 265 of file PndMvaSOMTrainer.h.

{
  return this->m_MapWidth;
};

GetNodeInitType()

MapNodeInitType PndMvaSomTrainer::GetNodeInitType ( ) const

inline

Definition at line 250 of file PndMvaSOMTrainer.h.

{
  return this->m_InitMode;
};

GetNumIterations()

size_t PndMvaSomTrainer::GetNumIterations ( ) const

inline

Number of iteration (epochs, learning steps).

Definition at line 280 of file PndMvaSOMTrainer.h.

{
  return this->m_NumIterations;
};

GetNumNodes()

size_t PndMvaSomTrainer::GetNumNodes ( ) const

inline

Returns

The total number of map nodes.

Definition at line 275 of file PndMvaSOMTrainer.h.

{
  return (this->m_MapWidth * this->m_MapHeight);
};

GetSigmaZero()

double PndMvaSomTrainer::GetSigmaZero ( ) const

inline

Definition at line 240 of file PndMvaSOMTrainer.h.

{
  return this->m_sigmaZero;
};

GetTheMap()

std::vector< PndSomNode * > const & PndMvaSomTrainer::GetTheMap ( ) const

inline

Returns

The actual SOM.

Definition at line 215 of file PndMvaSOMTrainer.h.

{
  return this->m_TheMap;
};

InitMap()

virtual void PndMvaSomTrainer::InitMap ( )

virtual

Initialize the map according to the given scheme.

printMapGrid()

inline

Definition at line 260 of file PndMvaSOMTrainer.h.

{
  this->m_MapHeight = val;
};

SetMapWidth()

void PndMvaSomTrainer::SetMapWidth ( size_t  val )

inline

Definition at line 270 of file PndMvaSOMTrainer.h.

{
  this->m_MapWidth = val;
};

SetNodeInitType()

void PndMvaSomTrainer::SetNodeInitType ( MapNodeInitType  val = SOM_RAND_FROM_DATA )

inline

{
  this->m_sigmaZero = val;
};

TrainBatch()

virtual void PndMvaSomTrainer::TrainBatch ( )

virtual

Train map using batch schema. All available data vectors are presented at once.

TrainOnline()

virtual void PndMvaSomTrainer::TrainOnline ( )

virtual

Train the map using Online scheme. Data vectors are presented one at a time.
