Interface IDecompositionStrategy

All Known Implementing Classes:

AbstractDecomposition, LatentDeterministicDecomposition, SmoothedFactorDecomposition

public interface IDecompositionStrategy

Interface for decomposition algorithms. The basic idea is to decompose a probability distribution p(x,y) by introducing a new variable z such that
\f$ p(x,y) = \sum_z p(x,z)p(z,y) \f$
This can be done through matrix decomposition.

Method Summary

Modifier and Type	Method and Description
void	decompose(BayesNet net, BayesNode node) decomposes a single conditional probability distribution.

Method Detail

decompose

void decompose(BayesNet net,
               BayesNode node)
        throws DecompositionFailedException

decomposes a single conditional probability distribution.

Parameters:

node - node contained in net

Throws:

DecompositionFailedException - when the decomposition failed. In this case, the strategy should not alter the network
