WebJan 3, 2024 · As Marcus has already pointed out; it's arbitrary to put the scale factor either into the forward or to the inverse DFT. However, the concept of energy equivalence in time and frequency domains (i.e., norm be preserved by the transform) requires that the scale factor be symmetrically distributed into both forward and inverse transforms. i.e; WebAug 25, 2024 · scaler = MinMaxScaler(feature_range=(-1,1)) If needed, the transform can be inverted. This is useful for converting predictions back into their original scale for reporting or plotting. This can be done by calling the inverse_transform () function. The example below provides a general demonstration for using the MinMaxScaler to normalize data. 1 2 irf covid waiver
