This module restores a file created by the Race Handicapping Prenetwork module (an exploded file with 2 horse comparisons) into a file that displays all horses in a single race on the same row (an imploded file). The exploded file must be an output file created by applying a trained network to an exploded pattern (.PAT) file or production (.PRO) file. The output file must also include the network inputs. You create this file by using the Attach module to combine the .OUT file side by side with the exploded .PAT file to create the final .OUT file.
Note: The procedures for using this module are the same for applying it to the original pattern file and for applying it to new data in a production file.
Determining Finish Place
In order to compare all horses in a single race and determine the finish place for each, this module sums up the finish places for each horse in all of the horse-to-horse comparisons for a single race (a single row in the original data file). The horse with the largest finishing place sum is assigned first place, the horse with the second highest finishing place sum is assigned second place, etc. If two or more horses have the same finishing place sum, the horse with the lower horse number (determined by column position in the original file) is given the place in question and the other horse is given the next finish place.
The following data should be displayed in the Module window by default from the Race Handicapping Prenetwork module:
Common Data is information that applies to the entire race (such as track condition or day of the week) rather than data that only applies to one horse.
Click on the "No Common Statistics" button if there is no Common Data.
Click on the "Number of Common Statistics" button if there is Common Data. Enter the number of statistics in the text edit box.
Enter the number of horses per race in the text edit box. The module works on the assumption that there are the same number of horses in all of the races in the file.
Enter the number of input statistics per horse. This number includes the number of individual statistics on each horse but does not include the finish place.
Use the File Menu to select an .OUT file or to view a pattern file. If you view the pattern file after it has been exploded, several label rows will appear at the top of the file. These rows contain information that will be used by this module to recreate the file.
Use the Implode Menu to begin processing the file or to interrupt processing.
Note: If you get an error message when imploding the file, it is probably because you have neglected to do one of the following:
1. Apply the trained network to the exploded file you are trying to implode.
2. Turn off the check boxes in the Apply Module that add extra columns into the .OUT (output) file, such as actual network outputs and differences between actual outputs and network outputs.
3. Run the Attach Module to put the inputs back into the .OUT file.
