Hello,

I extracted features by using GoogleNet, but I do not know how to train it to create classifier?

Thanks in advance

Yes. I have defined trainingSet.

If I understood you correctly, you would like to transfer learning to retrain GoogLeNet to create a classifier.

Please refer to the below documentation link which gives more information on Pretrained GoogLeNet convolutional neural network:

Has anyone tried to extract features from layers other than pool5-drop_7*7_s1? If so what is the syntax?

在 MATLAB Online 中打开

use some layer as the feature . then you can use it for other classifier

    net = googlenet;
    inputSize = net.Layers(1).InputSize;
    imds = imageDatastore(dbpathSave)
    augimdsTrain = augmentedImageDatastore(inputSize(1:2),imds );
    %%Extract Image Features
    layer = 'loss3-classifier';%1000
    featuresTrain = activations(net,augimdsTrain,layer,'OutputAs','rows');
