getting “KeyError” while implementing Z-score on a dataset

I have been trying to implement z-score normalization to all of the numeric values present in combined_data with the following code: Here, combined_data is the combination of training and testing datasets as a dataframe and passed through one-hot encoding. I am seeing the following error: The dataset combined…

Denormalization of output from neural network

machine-learning neural-network normalization python

I have used the MinMax normalization in order to normalize my dataset, both features and label. My question is, it’s correct to normalize also the label? If yes, how can I denormalize the output of the neural network (the one that I predict with the test set that is normalized)? I can’t upload the…
