This is my first attempt at writing a neural network and I am experiencing immense difficulty in reducing the error value which is relatively high and thus reduces the accuracy of the model.
library(neuralnet)
normalize <- function(x) {
return ((x - min(x)) / (max(x) - min(x)))
}
df <- read.csv('C:/Users/CaitlinG/data.diabetes.csv', header=T)
df <- as.data.frame(lapply(df, normalize))
training <- df[1:614,]
testing <- df2[615:768,]
my.neural.net <- neuralnet(Outcome ~ Pregnancies + Glucose + BloodPressure + SkinThickness + Insulin + BMI + DiabetesPedigreeFunction + Age, data=training, hidden=c(3,1), linear.output= F, threshold = 0.01)
df <- apply(df, 1, function(row) all(row != 0))
my.neural.net$result.matrix
plot(my.neural.net)
r neural-network

Welcome to Code Review. Your question is rather sketchy. Please tell us more about what your CSV file looks like and what you intend to calculate.
