'T5' generates almost the same input!

Beginners

I have a dataset containing 162 rows. The sample is like INPUT: ‘T4aN1M0 Stage IIIA disease’, OUTPUT: ‘STAGE:3a|T_prefix:|T:4a|N:1|M:0’. I have followed this summarization notebook from examples. I have tried training the model for multiple epochs( 3, 10, 15, 30 ) but the model can not capture the relationship between input and output. This is the output generated by the model. INPUT: ‘cT1bN3M1c stage IVB’ OUTPUT: ‘stage IVB stage stage cT1bN3M1c stage’. I would appreciate it if you could help me. Thanks in advance.

An interesting problem. Maybe you would provide more details. For example：

  1. the training dataset size?
  2. steps in your training?
  3. how training loss changes?
