Implementation for ICLR2022 paper Differentiable Prompt Makes Pre-trained Language Models Better Few-shot Learners.

• ❗NOTE: The code has been reorganized and we also provide a paper-list at PromptKG.

Environment

• python@3.6
• Use pip install -r requirements.txt to install dependencies.
• wandb account is required if the user wants to search for best hyper-parameter combinations.

Data source

• 16-shot GLUE dataset from LM-BFF.
• Generated data consists of 5 random splits (13/21/42/87/100) for a task, each has 16 samples.
  • The generation process follows LM-BFF here.

How to run

• To train / test on a data split from a single task with specific parameters, use run.py.
  • For customized training & evaluation, you can modify based on the sample configuration file config/sample.yml.

$ python run.py -h  
usage: run.py [-h] [--config CONFIG] [--do_train] [--do_test]

optional arguments:
  -h, --help            show this help message and exit
  --config CONFIG, -c CONFIG
                        Configuration file storing all parameters
  --do_train
  --do_test

• To search optimal hyper-parameters for each task and reproduce our result, please use sweep.py:
  • Please refer to documentation for WandB for more details.
  • ❗NOTE: we follow LM-BFF in that we search optimal sets of hyper-parameters on different data splits respectively.

$ python sweep.py -h
usage: sweep.py [-h] [--project_name PROJECT_NAME] --task_name TASK_NAME
                [--data_split {13,21,42,87,100}]
                [--pretrain_model PRETRAIN_MODEL] [--pet_method {pet,diffpet}]
                [--random_seed RANDOM_SEED] [--max_run MAX_RUN]

optional arguments:
  -h, --help            show this help message and exit
  --project_name PROJECT_NAME
                        project name for sweep
  --task_name TASK_NAME
  --data_split {13,21,42,87,100}
                        few-shot split-id for GLUE dataset
  --pretrain_model PRETRAIN_MODEL
                        name or path for pretrained model
  --pet_method {pet,diffpet}
                        prompt encoding method
  --random_seed RANDOM_SEED
                        random seed for training
  --max_run MAX_RUN     maximum tries for sweep
