public class BIFReader
Builds a description of a Bayes Net classifier stored in XML BIF 0.3 format.
For more details on XML BIF see:

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. |
java.lang.String |
getContent(org.w3c.dom.Element node)
Returns all TEXT children of the given node in one string. |
java.lang.String |
getFileName()
returns the current filename |
int |
getNode(java.lang.String sNodeName)
getNode finds the index of the node with name sNodeName and throws an exception if no such node can be found. |
java.lang.String |
getRevision()
Returns the revision string. |
TechnicalInformation |
getTechnicalInformation()
Returns an instance of a TechnicalInformation object, containing detailed information about the technical background of this class, e.g., paper reference or book this class is based on. |
java.lang.String |
globalInfo()
This will return a string describing the classifier. |
static void |
main(java.lang.String[] args)
Loads the file specified as first parameter and prints it to stdout. |
int |
missingArcs(BayesNet other)
Count nr of arcs missing from other network compared to current network Note that an arc is not 'missing' if it is reversed. |
BIFReader |
processFile(java.lang.String sFile)
processFile reads a BIFXML file and initializes a Bayes Net |
BIFReader |
processString(java.lang.String sStr)
|
int |
reversedArcs(BayesNet other)
Count nr of reversed arcs from other network compared to current network |
void |
Sync(BayesNet other)
synchronizes the node ordering of this Bayes network with those in the other network (if possible). |
