Method Detail

saveReadable

public static void saveReadable(java.lang.String gibbsmodel)

read

private static double[][] read(java.lang.String filename)

Parameters:

string -

charDouble

public static char charDouble(double d,
                              double max)

create a string representation whose grey value appears as an indicator of magnitude, using one digit per element.

Parameters:

d - value

max - maximum value

Returns:

saveShades

public static void saveShades(java.lang.String filename,
                              double[][] a,
                              double max,
                              java.lang.String comment,
                              boolean transposed,
                              java.lang.String additional)

save the matrix as a "shade" file, with optional additional information on the non-topics (that should be along rows). The method currently can save theta (with a ".doc" file in the additional argument) and phi (with the isPhi flag set and a ".vocab" file in the additional argument).

Parameters:

filename - target file name

a - matrix

max - normalisation

additional - information about non-topics (put to row starts)

readList

public static java.util.Vector<java.lang.String> readList(java.lang.String filename)

Read a list from the associated file name, depending on the type of file, the format is interpreted.

Parameters:

filename -

Returns:

readDocList

static java.util.Vector<java.lang.String> readDocList(java.lang.String file)
                                               throws java.io.IOException

reads the document names from a file

Throws:

java.io.IOException

readActorsList

static java.util.Vector<java.lang.String> readActorsList(java.lang.String file)
                                                  throws java.io.IOException

reads the actors list from a file with format name : id (on each line)

Throws:

java.io.IOException

readVocabulary

static java.util.HashMap<java.lang.Integer,java.lang.String> readVocabulary(java.lang.String file)
                                                                     throws java.lang.NumberFormatException,
                                                                            java.io.IOException

reads the vocabulary from a file with format id = termstring (on each line)

Throws:

java.lang.NumberFormatException

java.io.IOException
