imageInputLayer Normalization - Data normalization options

Hello,

In layer = imageInputLayer(inputSize,Name,Value), it is mentioned that the Normalization value can take 'zerocenter', 'zscore', 'rescale-zero-one', etc.

When choosing 'rescale-zero-one' as a 'Normalization' value I am getting an error telling me that only 'zerocenter' and 'none' can be taken as input for 'Normalization'. I checked imageInputLayer function and it is correct only these options exist (I am using MATLAB R2019a).

Do the other options exist in other MATLAB versions? Is it possible to use them?

Thank you in advance for your help!

Hi Andrea,

The 'rescale-zero-one' normalization option was added in R2019b, so you would need to update to at least that release to be able to make use of it!

sir，may be you should update MATLAB version, such as 2021

inputlayer = imageInputLayer([28 28 3],'Name','input', 'Normalization', 'rescale-zero-one')

inputlayer = 
  ImageInputLayer with properties:

                      Name: 'input'
                 InputSize: [28 28 3]

   Hyperparameters
          DataAugmentation: 'none'
             Normalization: 'rescale-zero-one'
    NormalizationDimension: 'auto'
                       Max: []
                       Min: []

Okay I will try although I have MATLAB 2019a.

Thank you for your help.
