Hello

I have LSTM network with database created. I have configure the network to use 70% of data for trainig and 30% for testing. Please how do I setup validation in the training option? I am stuck at this point...

for i= 1:rt-7012 %% this gets 70% of database content
    GHITrain{i,1}= Database{i,1};
end
restTrain= resultDatabase(1:rt-7012);
 options= trainingOptions('adam',...
    ExecutionEnvironment = 'auto',...
    MaxEpochs = Epoch,...
    MiniBatchSize = miniBatchSize,...
    InitialLearnRate= 1e-4,...
    Plots = 'training-progress');

在 MATLAB Online 中打开

 options= trainingOptions('adam',...
    ExecutionEnvironment = 'auto',...
    MaxEpochs = Epoch,...
    MiniBatchSize = miniBatchSize,...
    InitialLearnRate= 1e-4,...
    'ValidationData',{inputVal, targetVal}, ...   %<----- specify here 
    Plots = 'training-progress');
