Hi Andreea,
Firstly, glad to hear your starting your journey of deep learning in MATLAB!
Your code will likely look like this:
imds = imageDatastore('MyImageFolder', ...
'IncludeSubfolders',true, ...
'LabelSource','foldernames');
[YPred,scores] = classify(mytrainedNet,imds);
idx = randperm(numel(imds.Files),4);
figure
for i = 1:4
subplot(2,2,i)
I = readimage(imds,idx(i));
imshow(I)
label = YPred(idx(i));
title(string(label));
end
I would also recommend studying this example. It shows the suggested workflow for performing transfer learning :
