When using Data augmentation is it ok to validate only with the original images?
문제
I'm working on a multi-classification deep learning algorithm and I was getting big over-fitting:
My model is supposed to classify sunglasses on 17 different brands, but I only had around 400 images from each brand so I created a folder with data augmented x3 times, generating images with these parameters:
datagen = ImageDataGenerator(
rotation_range=30,
width_shift_range=0.2,
height_shift_range=0.2,
shear_range=0.2,
zoom_range=0.2,
horizontal_flip=True,
fill_mode='nearest')
After doing so i got these results:
I don't know if it's correct to do the validation only using the original images or if I have to use also the augmented images for the validation, also is strange for me to get higher accuracy on the validation than the training.
