KNIME implementation of RandomForest

KNIME Analytics Platform

hi all,

I was comparing the result of random forest algorithm in KNIME random forest (and tree ensemble) node and in R (using randomForest package). I always get better performance in KNIME compared to R. Great!!!

However, I tried to adjust the parameter in R and in KNIME so that it will have similar performance result but I am not able to do so. Anyone knows which parameter corresponds to what in KNIME node and R?

Hi Pkusuma,

this will never be possible. The random forest is based on random parameters. You can fix those in KNIME using the seed, but in R you can not get the same tree as learned in KNIME, only by chance.

Best regards, Iris
