Invert MinMaxScaler from scikit_learn

Question

To feed my generative neural net, I need to normalize some data between -1 and 1.

I do it with MinMaxScaler from Sklearn and it works great. Now, my generat

Answer 1

def rev_min_max_func(scaled_val):
    max_val = max(df['target'])
    min_val = min(df['target'])
    og_val = (scaled_val*(max_val - min_val)) + min_val
    return og_val
df['pred_target'] = scaled_labeled_df['pred_scaled_target'].apply(lambda x: rev_min_max_func(x))

Even this works for me!
