Hi Carnë!
I successfully installed and tested LIBSVM 3.17 in OCTAVE 3.6.4. I
followed the instructions as detailed in 2 LIBSVM readme's, in the
subdirs windows as well as MATLAB. Reading them very carefully, adding a
bit of details, and neglecting all the instructions as found on the
Internet with the help of my best friend Google did the trick. It was
typically a case of too many and to contradicting information.
I must sincerely apologize to Chih-Chung Chang and Chih-Jen Lin, and to
you for the noise. Sorry about that.
The PS states how I did it.
I am able to use LIBSVM as I wanted, so my problem is solved. This does
not change my original offer: If there is anything I can do, please let
me know.
Kind regards,
Hans Lodder
PS: Install and test LIBSVM
Step 1 is optional. If you have already installed OCTAVE there is no
need to repeat it. Mind though the directory name.
My platform:
Windows 8 Professional 64-bits
OCTAVE compiled with MingW
Tools: 7-zip, Notepad++
1. Download, install, and test OCTAVE
a. Download octave into the directory C:\octave
Link(MingW):
http://sourceforge.net/projects/octave/files/Octave%20Windows%20binaries/Octave%203.6.4%20for%20Windows%20MinGW%20installer/Octave3.6.4_gcc4.6.2_20130408.7z/download
b. Install OCTAVE
Unzip with 7-zip in place (option 'here')
c. Test OCTAVE
1 + 1
ans = 2
2. Download, install, and test LIBSVM
a. Download LIBSVM into the directory c:\octave\downloads
Link:
http://www.csie.ntu.edu.tw/~cjlin/cgi-bin/libsvm.cgi?+http://www.csie.ntu.edu.tw/~cjlin/libsvm+zip
b. Install LIBSVM
Unzip with 7-zip in place (option 'here')
If not already done so, start OCTAVE. In OCTAVE
ls
cd \octave
cd downloads
cd matlab
make
c. Test LIBSVM
[heart_scale_label, heart_scale_inst] = libsvmread('../heart_scale'); %
load the test data
model = svmtrain(heart_scale_label, heart_scale_inst, '-c 1 -g 0.07'); %
create the model
[predict_label, accuracy, dec_values] = svmpredict(heart_scale_label,
heart_scale_inst, model); % test the training data
Result:
Accuracy = 86.6667% (234/270) (classification)
