nnet library and FANN package'm
Hello !
I'd like to know to which of the FANN package network corresponds the R nnet
network ?
In more details, what is the R nnet activation function, what is the
training algorithm (rprop, quickprop, ...) ? Also, it seems that the R nnet
"decay" parameter in nnet corresponds to the "learning_rate" parameter in
FANN. Correct ?
Many thanks in advance !
