Problems in the above code:
(1) I want to predict my first three columns which depends on 41 rest of colums? I want to predicted them one by one actual vs predicted in plots. I not sure whether the above code is doing the same or not??
(2) Just after the training in above code, why this mean, stdv has been caculate for all training data and testing data? Training and testing dataset consist on my 41 independent variables. Each variable has different sense that why mean or stdv looking not sense to this code? Is mean and stdv for single variable will be suitable in ANN? (according to understanding)?
(3) This is my step by step working: I want to make 90% training and 10% testing, then want to train the ANN. Then validate and select best neural network. Then want to predict 2 last values of first 3 columns in data.csv file from optimum ANN?
(4) At the end, I want to make sure from experts over this plate form which verify my code whether its doing the following tasks correctly or not ??
(5) Is after training the dataset for 45 variables, I can predict 1 variables out of 3? then variable no 2 and 3 ? Is the results get from the train model will be reliable for predicting individual variable? It's much confusing to me? Please clerify ? Please
I'll be very thankful to experts for timely response?
