The Data File

The format for the data file was designed to be readable to humans. For the following description it is assumed that the network has l inputs.

Each tuple consists of:

The tuples are separated by a semicolon (';'), the last line may be concluded by a semicolon or by a dot ('.').

Here are some lines from an example data file with ten input attributes; the numbers used show the various possible formats recognized.

 0.233 0.12 -1 0.99   -0.121   .5 1 0.001 0 -1 : 3 ;
 1 -0.5 -0.1 -.99 0.21 0.45 1 -0.911 0 -0.8181 : 0 ;
 ...
 -1 0.5 -0.01 0.99 -1 -1 1 -0.11 0.1 -0.1199   : 4 .

This file format is referred to as `long file format' because it stores the information of the input vector and the output class. This file type can be used for training the network and for testing the performance of the network. A `short file format' containing only information about the input vectors, is used in the working mode. New input patterns are presented and the response of the system is calculated. The following lines are taken from a typical `short' file:

 0.913 -0.2 -1 0.119   0.11   .95 0.1 0.001 1 -1 ;
 0 -0.5 -0.1 -.9 0.21 0.5 -0.91 -0.11 0.10 -0.11 ;
 ...
 -0.2 0.2 0.01 0.99 -0.75 -1 0 -0.11 -0.341 0.19 .
