29 Dec 2012	Random Forest Creates an ensemble of cart trees similar to the matlab TreeBagger class.	fairy	I have found the reason.Because the Data mat is integral not double.	Comment only
23 Dec 2012	Random Forest Creates an ensemble of cart trees similar to the matlab TreeBagger class.	fairy	Thanks Leo! With your help,I have compiled succed ! by the way,the line 24 should change to saved_logs[j] = log((double)(j+1))/log(2.0); ..... Thanks Leo again.	5
22 Dec 2012	Random Forest Creates an ensemble of cart trees similar to the matlab TreeBagger class.	Leo	Hi fairy, lcc is not a cpp compiler. Using the Visual Studio compiler I think the following should do the trick. in GBCC.cpp change line 24 to saved_logs[j] = log(j+1)/log(2); line 115 to if (diff_labels[nl]>0) bh-=diff_labels[nl](log(diff_labels[nl])/log(2)-log(sum_W)/log(2)); line 151 to if(diff_labels_l[nl]>0) ch-=(diff_labels_l[nl])(log(diff_labels_l[nl])/log(2)-log(sum_l)/log(2)); and line 152 to if(diff_labels_r[nl]>0) ch-=(diff_labels_r[nl])*(log(diff_labels_r[nl])/log(2)-log(sum_W-sum_l)/log(2)); Hope this solves it.
