how can I replace the softmax layer with another classifier as svm in convolution network

4 views (last 30 days)
I made deep learning application that using softmax
layers = [ imageInputLayer(varSize); conv1; reluLayer;
convolution2dLayer(5,32,'Padding',2,'BiasLearnRateFactor',2);
reluLayer()
maxPooling2dLayer(4,'Stride',2);
convolution2dLayer(5,32,'Padding',2,'BiasLearnRateFactor',2);
reluLayer()
maxPooling2dLayer(2,'Stride',2);
convolution2dLayer(5,64,'Padding',2,'BiasLearnRateFactor',2);
reluLayer();
maxPooling2dLayer(4,'Stride',2)
fc1;
reluLayer();
fc2;
reluLayer();
%returns a softmax layer for classification problems. The softmax layer uses the softmax activation function.
softmaxLayer()
classificationLayer()];
I want to use SVM and random forest classifiers instead of softmax. and use a deep learning for feature extraction. I hope I can get a link for a tutorial.

Thanks for your answer but I don't want to use pre-trained models. I want to design mine and use it as a feature extraction.

the only possible solution is to save the extracted features by the deep model , then use this features as an input to the SVM or any other wanted classifier.
