How to visualize the features of the vision transfomer after training using t-sne visualizion?
example of vision transformer: https://se.mathworks.com/help/deeplearning/ug/train-vision-transformer-network-for-image-classification.html
and t-sne visualization of CNN: https://se.mathworks.com/help/deeplearning/ug/view-network-behavior-using-tsne.html
I could not apply the same in vision transformer beacuse there are an error during using actication function as follows:
earlyLayerName = "'encoderblock1_mha1";
pool1Activations = activations(net,...
augimdsTrain,earlyLayerName,"OutputAs","rows");

From what I gather, you are following the MATLAB examples “Train Vision Transformer Network for Image Classification” and “View Network Behavior Using tsne” to visualise the results of the network activations of a trained vision transformer. You are encountering an error in the process.
The line of code where you are encountering the error is trying to refer to a non-existent layer, assuming you are using the MATLAB default implementation of the “visionTransformer” network. By analysing the network, we can see the layer is named “encoderblock1_mha” and not “encoderblock1_mha1”. Unless you have renamed and replaced the layer, passing the correct layer name shall eliminate the result.
I hope you find the above explanation and suggestions useful!

Hi Mahmoud
Are you using the same data as mentioned and included in the examples?
