INSTALLATION FOR WINDOWS
4
The archive contains source files of the command line application and additional folders with MATLAB functions and samples. Windows executables are in the subfolder
windows. The PSVM can be started as follows
• open a command window
• change into the subfolder windows
• type psvm
or within MATLAB:
• start MATLAB
• change into the subfolder matlabdemo
• type startup
• available commands: psvmtrain, psvmpredict,
and psvmgetnp, psvmputnp, psvmkernel, psvmsmo
1.2
Requirements
To produce the executables from the sources, a C++-compiler with standard libraries
is required. The software produces output for visualizing graphs of hyperparameter selection, ROC, and significance testing. If you want to use them, ’gnuplot’ is required.
The gnuplot webpage is at http://www.gnuplot.info/download.html.
Select and install the latest release file appended with “W32”. Connect the filename
extension “.plt” with the gnuplot application to view the graphs by clicking at the corresponding script files.
1.3
Compilation of the Command Line Application
The needed source files for the command line application are:
psvm.cpp
psvm.h
psvmparse.cpp
psvmparse.h
The precompiler option -D float can be used to reduce the internal precision from
double to float. This saves memory costs, but may increase computational time. Another flag is for switching the file handling: If C TXT is defined by the precompiler
option -D C TXT, all input and output files were extended with ’.txt’.
