Some issues encountered in fine-tuning the T5 model

[Carrot-r]

Hi, thank you very much for your outstanding work in the field of thinking chain reasoning. During the process of reproducing the project, I have some questions that I would like to consult with you for assistance in resolving. When I was fine-tuning the T5 model using the custom_train.py file, there was this output on the console:

1、The training console will output some "VALIDATION-EXAMPLES" for each round of training. Can I understand it as testing the training effectiveness by using these questions from "VALIDATION-EXAMPLES" after training for one round? If that's the case, how were these "VALIDATION-EXAMPLES" selected? What kind of rules were used for selection?
2、What is the difference between the field "question" and the field "prompt" in "VALIDATION-EXAMPLES"? I guess after listing these issues, should we feed them to the fine tuned model for testing, feed it the "prompt field", and output the "completion" field? If that's the case, is the "prompt" field missing "let's think step by step"?
3、If I fine tune the T5 model, does the data I use only need to be from the B_text-davinci-002__C_zs_cot directory? If data needs to be modified or enhanced, only corresponding modifications can be made in this directory. Is this the case?

Looking forward to your reply！！

Thanks for your interest in our work :)

1. These were selected without any deep thought. We simply wanted to sanity-check the training process.
2. The question is the original question from the benchmark dataset, and the prompt is the actual text prompt that is fed to the language model (during training AND inference)
3. I think you should look into the data preprocessing pipeline to see where you want to make your own modifications. I don't remember exactly. I guess that modifying the json file (from which the code fetches the training data) is the easiest way, but I wouldn't recommend it for running and keeping track of various experiments

Thank you for your prompt reply!
In question 2, I would like to confirm if the content of "question" and "prompt" should be the same? Because from the output of the console, their content is the same. But since "prompt" needs to be fed to the model, has it automatically added "let's think step by step" in the program? Can you tell me the specific implementation location of the program?

[Namgyu Ho]

Yep, the formatting of the prompt depends on where it is used. Formatting is implemented in src/data/format.py
