Training Data Ideal Approach for Transfer Learning

If the classes you are working on overlap with the images the model was trained on, you can add pre-trained data to the mix. Do measure if this needs to be done since the pre-trained model might already perform well on classes it was trained on.

If you are classifying images of you and your friend, odds are good that the pre-trained dataset doesn’t have either of your images. Adding irrelevent images won’t do any good.
