'ValidationData' is not a recognized parameter. For a list of valid name-value pair arguments, see the documentation for this function.

Hi, Please help me to solve this problem.

I am trying to specify training options for CNN. In the moment of 'ValidationData' I am getting error. Traing options:

options = trainingOptions('sgdm', ...
    'MaxEpochs',4, ...
    'ValidationData',imdsValidation, ...
    'ValidationFrequency',30, ...
    'Verbose',false, ...
    'Plots','training-progress');

Error:

Error using nnet.cnn.TrainingOptionsSGDM.parseInputArguments (line 176)
'ValidationData' is not a recognized parameter. For a list of valid name-value pair arguments, see the
documentation for this function.
  Error in trainingOptions (line 144)
    args = nnet.cnn.TrainingOptionsSGDM.parseInputArguments(varargin{:});
  Error in CNN_mysample (line 59)
options = trainingOptions('sgdm', ...

In decription I found a note that says to "The validation data is not used to update the network weights. Turn on the training progress plot, and turn off the command window output." How can I turn off the command window output? Thank you all.

victor - which version of MATLAB do you have? Perhaps your version does not include the ValidationData parameter.

I am using matlab 2017a, does it support this parameter?

It looks like it was added in 17b; release notes. If you're doing deep learning in MATLAB, it makes sense to upgrade if at all possible(!)
