PERO

Reference code for Findings of Findings of ACL 2021 paper - Reordering Examples Helps during Priming-based Few-Shot Learning.

Dependencies

The code was written with, or depends on:

• Python 3.6
• Pytorch 1.7.0
• Transformers 3.4.0

Running the code

1. Create a virtualenv and install dependecies

   virtualenv -p python3 env
   source env/bin/activate
   pip3 install -r requirements.txt

2. Download data following instructions at https://github.com/ucinlp/autoprompt [2] and unzip in the same folder as this repository. For fact-retreival experiments, download LAMA [3] data from https://github.com/facebookresearch/LAMA and copy the relations.jsonl file into data/fact-retrieval/original/.
3. To Run classification tasks using 10 training examples: can be sst2 or sicke2b. can be pero or pero_abl (without sep token learning). <start_idx> specifies the trainin split, to reproduce results from the paper, use 0,10,20,30,40.

   bash run_clf.sh 0 <dataset> <mode> <start_idx> ./saved_models/outputdir1

4. Similarly, to run fact retrieval task:

    bash run_fact_retrieval.sh 0 <mode> <start_idx> saved_models/outputdir2
