Neural_Network-in-R

How to create a simple neural network using R

This is an already in built library which has dataset

library(datasets)

This gives information on what are the input variables in dataset considered.

names(infert)

Loading the neural net library

library(neuralnet)

Here we are trying to build a neural net with 2 input variables and one fixed output.

The hidden layers are numbered 2 here. We are traning the network here

nn <- neuralnet( case~age+parity+stratum+spontaneous+pooled.stratum, data=infert, hidden=2, err.fct="sse", linear.output=FALSE, likelihood=TRUE)

To know what a neural network data has

nn

plotting the neural network with 2 hidden layers and 2 inputs
