I need to utilize two different classifier to get best classification results. Since, it seems that they complement each other (not sure I am not expert btw). ROC characteristics are given below (testing scheme is 10-fold cross validation):
MetaCost [0 8; 1 0] Alternating Decision Tree (ADTree)
TP Rate FP Rate Precision Recall F-Measure ROC Area Class
0.973 0.62 0.119 0.973 0.212 0.696 YES
0.38 0.027 0.994 0.38 0.55 0.696 NO
Weighted Avg. 0.427 0.074 0.925 0.427 0.523 0.696
MetaCost [0 8; 1 0] Logistic
TP Rate FP Rate Precision Recall F-Measure ROC Area Class
0.604 0.161 0.245 0.604 0.348 0.771 YES
0.839 0.396 0.961 0.839 0.896 0.769 NO
Weighted Avg. 0.821 0.377 0.904 0.821 0.853 0.769
I have tried Voting but could not get desired results. Therefore, it is time to seek for expert help. Could you please advise me a solution, if possible?
Thanks in advance. Also, as a reminder I am not an expert.
EDIT: Best I can get:
Vote combines the probability distributions of these base learners:
weka.classifiers.meta.AdaBoostM1 -P 100 -S 1 -I 10 -W weka.classifiers.meta.MetaCost -- -cost-matrix "[0.0 8.0; 1.0 0.0]" -I 10 -P 100 -S 1 -W weka.classifiers.trees.ADTree -- -B 10 -E -3
weka.classifiers.meta.AdaBoostM1 -P 100 -S 1 -I 10 -W weka.classifiers.meta.MetaCost -- -cost-matrix "[0.0 8.0; 1.0 0.0]" -I 10 -P 100 -S 1 -W weka.classifiers.functions.Logistic -- -R 1.0E-8 -M -1
using the 'Product of Probabilities' combination rule
TP Rate FP Rate Precision Recall F-Measure ROC Area Class
0.706 0.204 0.231 0.706 0.348 0.825 YES
0.796 0.294 0.969 0.796 0.874 0.825 NO
Weighted Avg. 0.789 0.287 0.91 0.789 0.832 0.825
YES, whereas ADTree seems better forNO. I have triedBoostinglogistic, it did not worked either. – baris.aydinoz May 21 '12 at 14:53
