Conditional Random Forest in Knime?


I'm interested in use conditional random forest trees for variable selection, in order to reduce bias when correlated or heterogeneous-format variables are used. In R it is possible, but I'm looking for the same in Knime.  

Could you help me?


Hello svalerov,

unfortunately there is currently no native KNIME node that provides the functionality of conditional random forests.

But you can easily use the R nodes to perform tasks in R from within your KNIME workflow. The R package that you would want to use is called party and the corresponding algorithm cforest. In the following paper it is described (towards the end) how to use the different R packages to measure variable importance



Thanks Nemad for yoour help!
