hi, chayma, the attachment is the document of random forest using in R and in the Detail of function “importance” (page 6) you could see how the importance score of feature is calculated.
BTW, how did you do the random forest calculation? or would you mind to share your code of random forest if you using R ,too.
recently, I have been reading some technical documentation obout random forest but it is really hard for me. thanks in advance!
