I am working on Classification problems in Weka implemented in KNIME. I have developed some models from SVM, RandomForest and Decision Tree. These methods predicts quite similar to my dataset (prediction is nearly 72, 79, 80 % respectively), but i would like to combine these models into one model. I know, how to make these consensus model in EXCEL(manualy) but not in knime.
simple e.g. is
Observation 1 Actual SVM RF DT Consensus
1 Positive (P) P P P TP (All methods correctly classified)
2 Positive (P) N P P TP (Majority of Method in correctly classified)
3 Negative (N) P P N TN (Majority of Method in correctly classified)
4 Negative (N) N P P TN (Majority of Method correctly classified)
5 Negative (N) P P P FP (Majority of Method correctly classified)
Prediction % 40 40 60 80
i wanted to make automatic consensus model out of developed models. I am quite new to knime and i dont have programing skill. Could anyone explain this how to make ? is there any node for this ?
