How to run our experiments?

Data Preparation

We conduct experiments on CounterFact dataset. You can download the dataset here. run code clean_paraphrase.py to remove unrelated prefixes in paraphrase prompts in CounterFact and keep all prompts in the same format.

Demonstration Organization

We select first 2,000 records as test set. For each record, we use sentence transformers to retrieve 32 nearest neighbours from remaining records as in-context demonstrations. The indices of nearest neighbours are stored in corpus_idx.txt. You can also run code encode_facts.py and semantic_search.py to build corpus_idx.txt.

Main Experiments

IKE: python icl.py

PROMPT: python prompt.py

Other baselines: implemented by rome

Models for IKE

You can evaluate IKE based on different LLMs by specifying the model name of LLMs.

python icl.py --model_name [model name]

The model name can be ['gpt2-xl', 'EleutherAI/gpt-neo-1.3B', 'EleutherAI/gpt-j-6B', 'EleutherAI/gpt-neox-20b']
