I am trying to apply regression through CNN on 3ch of image data composed of RGB.
So, referring to https://kr.mathworks.com/help/deeplearning/ug/train-a-convolutional-neural-network-for-regression.html, I entered the following to compose the training data.
[XTrain,YTrain] = voltage_img;
The variable voltage_img is (434*343*3*310), which is 4-D. When I run the above code, I get an error saying that there are too many output arguments.
How can I fix it?
