I've been using the in built 'digitTrain4DArray' and 'digitTest4DArray' to train my own regression network, by replacing my own training images and validation images in the folder that these two commands pull from. In the original example, there are also 2 excel files that was used, 'digitTrain' and 'digitTest', which had both predictors (images and digits) and response (angle of rotation). I've collected numerical validation data of 'true' values to replace 'digitTest' (I believe this is right?), but I'm not sure what to do about replacing 'digitTrain'. My supervisor has said that I don't need any numerical data such as 'digitTrain', and that I can alter the built-in code to train the network with simply my training images, and comparing these against the validation images/values will be enough.
I've looked at the relevant codes and 'digitTrain4DArrayData' is dependent on converting a .csv file into a 4D array. Is there any way I can remove the numerical vector 'digitTrain', and just train using my images?
Sorry for the paragraph, would really appreciate some help, I'm quite confused a fairly stressed about this!
