PLOT_GAUSS(1)

NAME
plot_gauss -- Plot the structure of a Gaussian classifier.

SYNOPSIS
plot_gauss [-fparam file] [-fplot file]
[-fdescribe file] [-autoscale] [-no_text] [-no_graphics]

DESCRIPTION
Displays node structure for a previously trained Gaussian classifier. The graph can be scaled to display the whole structure or the scale can be left at a default value. The input nodes are represented by small black circles at the bottom of the graph. The input feature labels are written below these circles. The output nodes are represented by large white circles at the top of the graph. The output class labels are written above these circles. Lines connect each input node to each output node. The type of covariance matrices used for this classifier (full vs diagonal, grand vs per class) is written at the bottom of the graph.

EXAMPLE
gauss -train -create -pathdata $LNKHOME/data/class \
-finput XOR.train -fdescribe XOR.defaults \
-fparam gauss.param

plot_gauss -fparam gauss.param \
-fdescribe $LNKHOME/data/class/XOR.defaults

OPTIONS

--  Prints a list of all flags and arguments.

-fparam file
    Parameter file for previously trained gauss classifier.

-fplot file
    File to store generated gauss structure plot.

-fdescribe file
    Defaults file containing the class labels for the data base used to train the gauss classifier. If this flag is set, the terminal node classes will be indicated by the class labels. Otherwise, the class numbers will be used.

-autoscale
    Scale the plot vertically and horizontally so that all the nodes in the classifier are visible and the classifier fills the plotting window.

-no_text
    Only print the classifier structure. Do not print input or output labels.

-no_graphics
    Create the plot file, /fIfplot/fR, but do not display it in an olxplot window.

HISTORY
First written June 1994
Modified 19 April 1995, added no_graphics flag

BUGS
When plot2ps is used to generate a postscript file from the gauss plot file, the font for the node text may have to be scaled to match the scale of the plot.
