Re: libsvm

Hello,

I've made a simple test in libsvm on octave, with data provided by the same
libsvm soft

octave:2> [heart_scale_label, heart_scale_inst] =
libsvmread('../heart_scale');
octave:3> whos
Variables in the current scope:

   Attr Name                   Size                     Bytes  Class
   ==== ====                   ====                     =====  ===== 
        heart_scale_inst     270x13                     40592  double
        heart_scale_label    270x1                       2160  double

Total is 3780 elements using 42752 bytes

octave:4> model = svmtrain(heart_scale_label, heart_scale_inst, '-c 1 -g
0.07');
*
optimization finished, #iter = 134
nu = 0.433785
obj = -101.855060, rho = 0.426412
nSV = 130, nBSV = 107
Total nSV = 130
octave:5> [predict_label, accuracy, dec_values] =
svmpredict(heart_scale_label, heart_scale_inst, model);
Accuracy = 86.6667% (234/270) (classification)
octave:6> 

It seems to be working well.

I'll continue reporting.
