Jul 20, 2015 · First the neural network assigned itself random weights, then trained itself using the training set. Then it considered a new situation [1, 0, 0] and predicted 0.99993704. The correct answer was 1.

12.12.2010 · The following code runs the network (with 2 hidden layers) classifying ‘case’ (a binary variable) as a function of several independent varaibles. The neural network is estimated, and the results are stored in the data frame ‘nn.’ nn <- neuralnet ( case~age+parity+induced+spontaneous, data=infert, hidden=2, err.fct=”ce”, linear.output=FALSE)
