Constructor & Destructor Documentation

◆ ModelParameters() [1/2]

STK::ModelParameters< Clust::Poisson_ljk_ >::ModelParameters ( int nbCluster )

default constructor

Parameters

nbCluster the number of class of the mixture

Definition at line 43 of file STK_PoissonParameters.cpp.

                                                     : lambda_(nbCluster)
                                                     , stat_lambda_(nbCluster)
{}

◆ ModelParameters() [2/2]

STK::ModelParameters< Clust::Poisson_ljk_ >::ModelParameters ( ModelParameters< Clust::Poisson_ljk_ > const & param )

copy constructor.

Parameters

param the parameters to copy.

Definition at line 50 of file STK_PoissonParameters.cpp.

                                                     : lambda_(param.lambda_)
                                                     , stat_lambda_(param.stat_lambda_)
{}

Member Function Documentation

◆ lambda()

Real const & STK::ModelParameters< Clust::Poisson_ljk_ >::lambda	(	int	k,
		int	j
	)		const

inline

Returns: the intensity of the kth cluster and jth variable

Definition at line 126 of file STK_PoissonParameters.h.

126{ return lambda_[k][j];}

◆ releaseStatistics()

void STK::ModelParameters< Clust::Poisson_ljk_ >::releaseStatistics ( )

Release the computed statistics.

Definition at line 81 of file STK_PoissonParameters.cpp.

{
  for(int k=stat_lambda_.begin(); k<stat_lambda_.end(); ++k)
  { stat_lambda_[k].release();}
}

◆ resize()

void STK::ModelParameters< Clust::Poisson_ljk_ >::resize ( Range const & range )

resize the set of parameter

Definition at line 57 of file STK_PoissonParameters.cpp.

{
  for (int k = lambda_.begin(); k< lambda_.end(); ++k)
  {
    lambda_[k].resize(range) = 1.;
    stat_lambda_[k].resize(range);
  }
}

◆ setParameters()

template<class Array >

void STK::ModelParameters< Clust::Poisson_ljk_ >::setParameters ( ExprBase< Array > const & params )

inline

Set the parameters of the mixture model.

It is assumed that the array params is of size (nbCluster, nbVariable).

Definition at line 142 of file STK_PoissonParameters.h.

    {
      for(int k=lambda_.begin(); k<lambda_.end(); ++k)
      { lambda_[k] = params.row(k);}
    }

◆ setStatistics()

void STK::ModelParameters< Clust::Poisson_ljk_ >::setStatistics ( )

Set the computed statistics.

Definition at line 72 of file STK_PoissonParameters.cpp.

{
  for(int k=stat_lambda_.begin(); k<stat_lambda_.end(); ++k)
  {
    lambda_[k] = stat_lambda_[k].mean();
    stat_lambda_[k].release();
  }
}

◆ updateStatistics()

void STK::ModelParameters< Clust::Poisson_ljk_ >::updateStatistics ( )

update statistics of the parameters.

Definition at line 66 of file STK_PoissonParameters.cpp.

{
  for(int k=stat_lambda_.begin(); k<stat_lambda_.end(); ++k)
  { stat_lambda_[k].update(lambda_[k]);}
}
