Detailed Description

template<typename GUM_SCALAR, template< typename > class APPROX>
class gum::LoopySamplingInference< GUM_SCALAR, APPROX >

<agrum/BN/inference/loopySamplingInference.h>

class for making hybrid sampling inference with loopy belief propagation and an approximation inference method in Bayesian networks.

This class inherits of template class APPROX, which SHOULD be one of the 4 approximate inference methods (MonteCarlo, Weighted, Importance, Gibbs). It makes the inference with respect to the inherited class' method, after having initialized the estimators with the posteriors obtained by running LoopyBeliefPropagation algorithm.
