Hello there, Yes, I'd tried scale as well. I mean, I could do my preprocessing separately and it was working fine. I was just wondering how preProcess argument in train function works. As far as I know, when preProcess argument is set, it normalizes inputs but not outputs. Then I've figured we co

Hello, Have you tried alternative methods of pre-processing your data, such as simply calling scale()? What is the effect on convergence, for both the caret package and and the neuralnet package? There's an example using scale() with the neuralnet package at the link below: https://datascienceplu

Hello there, I am using caret and neuralnet to train a neural network to predict times table. I am using 'backprop' algorithm for neuralnet to experiment and learn. Before using caret, I've trained a neuralnet without using caret, I've normalized my input & outputs using preProcess with 'range' m
