Qnet 2000 |
Qnet may be started similar to all programs from the Start/Programs menu. It may also be started from Windows Explorer by double-clicking any ".net" file. A third method for invoking Qnet is to use its command line syntax (start from a DOS prompt, batch file or application). This method is especially useful for automating the AutoTrain process. Qnet's command line syntax is shown below:
[drive:\path\]qnet [-t -l -mt -ml -qcor -qrms] [[drive:\path\]filename]
where:
-t Starts Qnet in AutoTrain mode with the filename parameter set to the ".net" file that is to be trained (example: c\qnetv2k\qnet -t SphereDrag.net).
-l Starts Qnet in AutoTrain processing mode with the filename parameter set to the ".net" file that is to be analyzed/optimized (example: c\qnetv2k\qnet -l SphereDrag.net).
-mt Use this option to AutoTrain a group of ".net" files. The filename argument in this case is a file that lists the (fully qualified path/filenames) ".net" files. Each record (line) in the list file should contain a ".net" file to train. Qnet will then run in AutoTrain mode, training all networks in listed in the file (example: c\qnetv2k\qnet -mt TrainTheseNets.txt).
-ml Use this option to process a group of AutoTrained ".net" files. The filename argument in this case is a file that lists the (fully qualified path/filenames) ".net" files. Each record (line) in the list file should contain a ".net" file to process. Qnet will then run in AutoTrain processing mode, allowing the user to optimize and analyze each previously AutoTrained network model in the list (example: c\qnetv2k\qnet -ml TrainTheseNets.txt).
-qcor Must be used with the -t or -mt options. This causes Qnet to save the net file at the minimum RMS error in the test set. Do not use this option if you are not using test sets. By default, Qnet saves the last iteration. Regardless of the option set here, you may change the ".net" file that is saved with an AutoTrain processing/optimization run.
-qrms Must be used with the -t or -mt options.. This causes Qnet to save the net file at the maximum correlation in the test set. Do not use this option if you are not using test sets. By default, Qnet saves the last iteration. Regardless of the option set here, you may change the ".net" file that is saved with an AutoTrain processing/optimization run.
