Hi Friends,
I want to assign asymmetric cost values at the time training.
For example : For false negative cost should be 10 and for For false
positive it should be 1.
Can some help me with this.
Code:
svmFit <- train(Y ~ .,
data = train,
method = "svmRadial",
preProc = c("center", "scale"),
cost=5,
trControl = trainControl(method = "repeatedcv", repeats =
5,classProbs = TRUE))
So I need a way to force cost of 10 for false negative and 1 for false
positive at time of training.
Regards,
Bharat
