Random Forest keeps getting worse
Hi, I'm using different Methods to compare the results using the design from this tutorial:
Due to the runtime I initially set Random Forest to only 10 trees and only 5-fold cross-validation (Naive Bayes and Decision Tree were run with 10-fold).
This had NB with an f-score of 66.6, DT with 67.8 and RF with 62. I attributed this worse performance to it being only 5-fold so I ran it with 10-fold.
This time Random Forest had an f-score of 46.5!
How did that happen? Do I have to set RF up differently?
