java - Weka J48 changing option - no difference -



java - Weka J48 changing option - no difference -

i trying alter options j48 classifier, makes no difference in resulted tree.

my code:

j48 cls = new j48(); instances info = new instances(new bufferedreader(new filereader("somearfffile"))); data.setclassindex(data.numattributes() - 1); //was trying utilize -m 1 , -m 5, no difference string[] options = new string[1]; options[0] = "-c 1.0 –m 1"; cls.setoptions(options); cls.buildclassifier(data); //displaying j48 tree treevisualizer tv = new treevisualizer(null,cls.graph(),new placenode2());

after set value method working fine.

cls.setminnumobj(5);

any ideas how can utilize setoptions method instead of setminnumobj?

the problem how seek set options. options array should args array in main method, 1 string per element:

string[] options = {"-c", "1.0", "–m", "1"}; cls.setoptions(options);

otherwise won't work.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
