I've an image dataset with around 100 classes and the maximum number of images for one class is 59 whereas the minimum is 5. I try to split the data into training, validation and testing by using the following statement
[imdsTrain,imdsValidation, imdsTest] = splitEachLabel(imds,0.75,0.15,'randomize');
I got the error that training and validation data must have same labels.
I checked the imds and found that for classes having less number of images like 5, it puts 4 in training and 1 sometimes either in validation set and some in test data set. So all classes that are in training are not found in validation or test data set.
I solved it by increaing the validation percent to 0.2 instead of 0.15 but it doesn't seem a good solution.
Is there a way to split the dataset such that all classes are present in all 3 datasets? Preferably I want to make it using percentages and don't want to use integer such that it puts always 1 image in validation and test dataset.
