Overfitting problem in S3DIS dataset? 2021-9-12

[MichaleWong]

why I encounter overfitting problem? I used Area5 as the test dataset , after about 4 epoches, the test loss begin increasing obviously, the train loss looked well. I changed to use Area2 as test data, it is still overfitting?
The data I used is same to you, hdf5 file, I tried using xyz and rgbx'y'z' as features, still overfitting.
can you give me some suggestions
