| Post subject: | dfbuildrandomdecisionforest training |
I am converting my Mat(28539,7) to to real2d array for alglib:::dfbuildrandomdecisionforest training. I am confused about the class labels used, if these will be in last column or first coloum. From the documentation i reached on the decision that class labels will be in last coloum. But whn i put these in last coloumn, model training take a long time. while when i put it in the first coloumn model is built in just 4-5 mintuse. khalil |

I can confirm that the labels are last column. The training time depends on so many things (training data size, number of trees, etc.) I'm also new to this so I can't give you too many advices. :) |
