Customize Model

Hi, I am a begineer aboul ML
I would like to customize example model from tensorflow website
[Image classification  |  TensorFlow Core]

when training finished, I got 99% accuracy but when I using blinding test, it only 65% accuracy, I already use data augmentation and drop out.
Here is my problems

  1. Should I adding more layer or there is another way to improve accuracy?
  2. Is there any function or method help you analysis model so I can understand why this picture is false positive or true negative?

Thanks for your information

Hi @YLH, This is a problem of over fitting, to overcome this problem please try by adding regularization layers to the model, use early stopping techniques. Thank You.
