R caret nnet package in Multicore

Question

Can we train a neural network model in parallel using multicores by leveraging foreach package, nnet and caret packages ?

I only see randomforest implementation in p

Answer 1

doMC doesn't support R 3.2. you can use doParallel

library(doParallel);
cl <- makeCluster(detectCores())
registerDoParallel(cl)
tc <- trainControl(method="boot",number=25)
train(Species~.,data=iris,method="nnet",trControl=tc)
stopCluster(cl)
