I am right now trying to create an age detector by referencing human faces. I decided to use pretrained model from resnet50. However, when I refer to other age detectors found from github, I found out they did import a pretrained model, but do not freeze the CNN layers.
I thought that since CNN layers are kind of feature extractors, it is reasonable to freeze those layers. If so, what are the reasons for not freezing those CNN layers??
I really need you guys’ help! Trying to learn everything from scratch.
