Excite is the command used for running a network. Here is the syntax:
USAGE: Excite [options] Net Input Option Default -S Treat 'Input' as a script file holding inputfiles (off) -x ext Extension for outputfiles (act) -d dir Directory to store output files in (current) -m object Mark a unit, group or stream to be shown (outputs) -e Show error gradients (also does '-x grad') (act's) -w 'Winner takes all', highest activity =1.0, others =0.0 -b num For each frame, show the names of the n highest outputs -c Add a column, counting framenumber. (off) -B Output binary floats (4 bytes) (text) -X stream Output a stream (off) -s stream Output a softmax-stream (off) -n freq Print the names of the units every 'freq' frames (off) -h Select high (6 figures) resolution (2 figures) -T level Trace level (0)Excite can display activities of selected units or stream-vectors, but the default is to display the activities of all output units. The data can be outputted in several different formats and is written to a file with the same base name as "Input".
The -m option is used to mark a particular unit, group or stream to be monitored. There can be multiple -m options on the command line to monitor more than one object. If the command line has no -m options, the activities of all output units are selected.
If the output units are named, the -b option can be useful. It makes Excite output the names of the "num" units with the highest activity at each time (the list of "num" names is ordered by activity).
Just like the training tools, Excite can be run either with one input file, or with a list of files who will then be processed one by one. This is controlled with the -S option. If the -S option is chosen, then "Input" is treated as a script file holding list of filenames, otherwize "Input" is simply the file name.
USAGE: CResult [options] Net Input Option Default -S Treat 'Input' as a script file holding inputfiles (off) -m object Mark a unit or a group to be tested (all output units) -c Print confusion matrix (off) -n N Show "within-top-N" statistics (off) -x label Exclude frames were 'label' has highest target (off)The -m option is used to mark a particular unit or group to be evaluated. There can be multiple -m options on the command line. If the command line has no -m options, all output units are selected.
The -n option shows how well the classification network performes in cases when it failed to "choose" the correct class. It makes CResult show how often the correct class was within the N nodes with higest activity.
In some experiments, one or more classes are less interesting than the others, but they could still cover a large part of the data. In other words: the rare classes are the interesting ones, so including the less interesting but common classes in the statistics, blurs the picture. In these cases the -x option is useful since it removes the samples where the correct class is "label" from the statistics. "label" is the name of an output unit.
