# Further Normalization of Standardized data - ANN

I want to develop a regression model using the artificial neural network. For developing such a model I use standardised ( z-score normalised ) data.

given below is the sample data set. Here MAX is the real data But I am using MAX-ZS (these values are continues)

So my question is while developing the model do I have to perform further normalization such as Min-Max scaling on my training data? Any Kind of help is appreciated!

So you just have to scale the data once. Doesn't matter what scaler you are using. Just make sure to initialize the scaler with the training data and then use the same parameters to scale the test data.
The z-score normalized data (MAX-ZS) can be used directly to train the network.
