Just as explained in the title, i want to set binary categories to sub-folders which will become class labels for a deep learning application, but i am struggling to find the correct syntax to move forward with this step.
I assume you are working with image datastores and you're looking to create a dataset with images belong to two classes.
imageDatastore has a Name-Value pair called 'LabelSource'. When this property is set to 'FolderNames', all the images belonging to a a sub-folder will derive their labels from the folder name.
Since you can't have multiple sub-folders with the same name, you would have to organise all your data into two folders representing your two categories and then use the 'LabelSource' N-V pair with imageDatastore. Here's an example you might find helpful: Create ImageDatastore object
