Overview

This is the code for the ICLR 2023 paper "Leveraging Large Language Models for Multiple Choice Question Answering." It can be used to reproduce results in the paper and is designed to be extensible.

Setup

• Start by using your favorite package manager to install datasets, numpy, openai, pandas, scipy, tqdm, and transformers.
• Now register your API keys in api_sectrets.py. To do this, add a key and value for each API key you want to register to the dictionary in the get_api_key_by_name function. You'll need an OpenAI key for OpenAI API experiments, and a Jurassic key for Jurassic API experiments. You can use the existing keys or choose your own names for the keys.

Running Experiments

To run experiments and reproduce the results from the paper you will use main.py.

The positional command line arguments are:

• The name of the dataset to use (must be a key from the dictionary inside get_dataset_info in dataset_utils.py) e.g., "mmlu"
• The name of the model to use (must be a key in one of the dictionaries in get_model_by_name in models.py) e.g., "codex"
• The name of the prompting style to use (either "brown" (called CP in the paper) or "natural" (called MCP in the paper)
• The number of shots to use ("0" for zero-shot, "1" for one-shot, etc.)
• The name of the API key to use (must be a key from the dictionary inside get_api_key_by_name in api_secrets.py

The optional command line arguments are:

• --do_strong_shuffle: For strong shuffling as used in Appendix C
• --do_perm: For passing all permutations of each question to the model, as in the experiments in Section 4

Running main.py will save a pickle file with experiment results.

Analyzing Results

To analyze the results of an experiment (from its saved pickle file) you will use analyze.py. The positional and optional command line arguments are the same except for you don't need to supply the name of an API key to use. These arguments will be used to look up the saved experiment pickle file.

Other Functionality

• You can visualize prompts that will be used by an experiment with viz_prompts.py. The positional command line arguments are dataset name, style name, and number of shots (as you'd use with main.py). The optional argument --longest will show the longest prompt instead of a random one.
• You can add a custom model by adding a custom key and value to a dictionary in get_model_by_name within models.py.
• You can add a custom dataset by adding a custom key and value to the dictionary in get_dataset_info within dataset_utils.py.
