The i2b2 model did not reach the expected f1 value.

[neverneverendup]

Hello, thank you for your great work.
I trained myself on a ner model of i2b2014 without using a pre-trained model. But the result I got was only 89%, not 97% of what you said. I want to know what went wrong? And what should I do? Thank you. (ps: The training results should be viewed from this file named f1_score vs epoch number for all classes.pdf?)
