divergence(BayesNet other)
calculates the divergence between the probability distribution represented by this network and that of another, that is, \sum_{x\in X} P(x)log P(x)/Q(x) where X is the set of values the nodes in the network can take, P(x) the probability of this network for configuration x Q(x) the probability of the other network for configuration x |
int |
extraArcs(BayesNet other)
Count nr of exta arcs from other network compared to current network Note that an arc is not 'extra' if it is reversed. |

getContent(org.w3c.dom.Element node)
Returns all TEXT children of the given node in one string. |
