About 3 steps in training

[wuqun-tju]

Thanks for your excellent work!
In the process of training, there are 3 steps, the head of first two is linear, and the last one is dpt. I wonder whether it is neccessary to train linear head?
If we train dpt head directly without training linear head, is it right?

Hi,
from our limited experiments, we got slightly better results by training with the linear head first (I don't have numbers on hand to back it up though).
