how can I make sure the sow model is trained properly? #11

Closed TITC closed 3 years ago

TITC commented 3 years ago

I am following your detailed guidance step by step to training my own sow model, but I not sure what's the criterion of judging the model trained enough?

I want to make a tweak version in Chinese, so want to go deeper into your repo. XD

For the SOW model, you can look at metrics like perplexity, loss etc. to ensure that the training loss is creasing. But the quality would have to be determined qualitatively by looking at the rearrangements that are outputted by the system and if they make sense.

BTW, since you are working with Chinese, you may have to rework the alignment code, because current code uses some heuristics to align phrases that have been tuned for the English language but may not be ideal for others.

tldr;

  1. check the quality of the SOW training data generated by the create_sow_data.sh
  2. spot check the qual. of the generated outputs from the trained model.
