There are 50000 training images and 10000 test images. Mdl = fitcecoc( X , Y ) returns a trained ECOC model using the predictors X and the class labels Y. For deep learning, MATLAB provides automatic parallel support for multiple GPUs. Consequently, MATLAB Coder infers the properties from the example values. See Deep Learning with MATLAB on Multiple GPUs (Deep Learning Toolbox). How to make GUI with MATLAB Guide Part 2 - MATLAB Tutorial (MAT & CAD Tips) This Video is the next part of the previous video. Breast cancer diagnosis using clinical data was also developed.
