Method Detail

readBIF

public static BayesianNetwork readBIF(java.lang.String f)

Read a BIF file.

Parameters:

f - The BIF file.

Returns:

The Bayesian network that was read.

readBIF

public static BayesianNetwork readBIF(java.io.File f)

readBIF

public static BayesianNetwork readBIF(java.io.InputStream is)

Read a BIF file from a stream.

Parameters:

is - The stream to read from.

Returns:

The Bayesian network read.

writeBIF

public static void writeBIF(java.lang.String fn,
                            BayesianNetwork network)

Write a Bayesian network to BIF form.

Parameters:

fn - The file name to save to.

network - The network to save.

writeBIF

public static void writeBIF(java.io.File file,
                            BayesianNetwork network)

Write a Bayesian network to a BIF file.

Parameters:

file - The file to save to.

network - The network to save.

writeBIF

public static void writeBIF(java.io.OutputStream os,
                            BayesianNetwork network)

Write a Bayesian network to an output stream in BIF format.

Parameters:

os - The output stream to write to.

network - The network to write.

generateTable

public static java.lang.String generateTable(BayesianEvent event)

Generate a table, in BIF format.

Parameters:

event - The event to write.

Returns:

The string form of the table.

rollArgs

public static boolean rollArgs(BayesianEvent event,
                               int[] args)

Iterate through the event arguments in the BIF way, which is different than Encog's method.

Parameters:

event - The event to save.

args - The arguments.

Returns:

True if there is further to iterate.
