How can I do mutli-class classification with the 3D Unet?

Show older comments. Atallah Baydoun on 22 Aug Vote 0. Commented: Atallah Baydoun on 6 Nov The 3D Unet segmentation example features a binary class classification. I was tying to extend the example to multi-class classification but I kept on having a constant loss function. Was anyone able to perform multi-class classification with the 3D unet in matlab?

I have the same question 0. Class classification examples 1. Shashank Gupta on 27 Aug Cancel Copy to Clipboard. Helpful 0. Multiclass classifiers are very similar to binary classifier, you may need to class classification examples the last layer of your model to make the multiclass classifier output compatible with your model. There is a function available in MATLAB " pixelLabelDatstore", which can generate the pixel label images that in turn may be used as a label data target in your network for semantic segmentation.

Also, there can be many reasons to get a constant loss function, Data imbalance could be one. If that does not help, try using an adaptive learning rate for your network. Also check the target images before feeding it to your network, sometimes the target and predictive images comes out to be transpose of each other because of how the MATLAB handles the data.

May be 3D tumor segmentation example can help you set up your model. Atallah Baydoun on 29 Aug Thank you Shashank. I am very familiar with the brain 3D Unet semantic segmentation example. Before even posting this question, I had done all the steps that class classification examples have recommended with no improvement. I also have tried to class classification examples some time ago with the Matlab class classification examples regarding the generalization to multi-class but still, the issue was not solved.

Any help would be appreciated! Shashank Gupta on 30 Aug Hi Attallah. It can also happened that the optimizer stuck at some saddle class classification examples and not able to come out from there, May be a different optimizer can help although I can safely assume you must have tried this. I cannot think of any more causal research examples as of now.

Hope this give you some lead. Atallah Baydoun on 6 Nov Hey Shashank. Another technical question came up and I was wondering if you can help with understanding the choice of data for the minibatch. Let us assume that we have 20 images, and we chose only one patch per image. This will give us a total of 20 patches. Let us also suppose that we chose our minibatch size to be 5.

At each iteration, trainnetwork will choose 5 patches among the 20 to create its minibatch. How is the selection process done? Is it completely random? I have tried to debug the trainNetwork code but I couldn't find anything? See Also. Tags 3dunet multi-class classification semantic segmentation deep learning u net. Start Hunting!
