MATLAB: Does the input data for neural network for classification should be normalized

Deep Learning Toolboxneural network

Hi everyone, i tried to create neural network for classification using nprtool but i still can't reach a good accuracy however i tried changing the training function and the number of hidden layer neurons and the size of the input so when i was looking for a solution i found that i should normalize the input data so i want to know should i do this with matlab. This is an example of my input data:
please i really need help ?

Best Answer

MATLAB automatically normalizes input and target data and unnormalizes output results.
However, I typically normalize my regression inputs and targets to have zero mean and unit standard deviation jn order to locate and remove or modify outliers.
Hope this helps.
Thank you for formally accepting my answer
