Code for the ACL-2022 paper "Knowledge Neurons in Pretrained Transformers"

Introduction

This project helps you to reproduce all the results presented in our work about knowledge neurons, including calculating the knowledge attribution scores, identifying knowledge neurons, computing all the statistics, and plotting all the figures.

Code Usage

First please change the working directory to src/.

Calculate the Attribution Scores

Run bash 1_run_mlm.sh param1, where param1 is the relation name to analyze, such as "P101". You can write a script to run this command for each of the 34 relations. This command will calculate the attribution scores for all the facts.

Identify Knowledge Neurons

Run bash 2_run_kn.sh. This command will identify and refine knowledge neurons for each fact, and give their statistics along with a figure about the knowledge neuron distribution.

Modify Knowledge Neurons

Run 3_run_modify_activation.sh. This command will modify the activation values of knowledge neurons and record the corresponding results.

Check Knowledge Neuron Activation for Prompts

Run 4_run_distant.sh. This command will check the activation values of knowledge neurons for different types of prompts crawled from web pages.

Produce Activating Prompts

Run 5_run_trigger_examples.sh. This command will produce activating prompts.

Update Facts

Run 6_run_edit.sh param1 param2, where param1 and param2 are two hyper-parameters. In our paper, they are set to 1 and 8, respectively. This command will edit sampled facts.

Erase Relations

Run 7_run_erase.sh param1, where param1 is the relation name to erase. This command will erase a relation. In our paper, we try to erase P19, P27, P106, and P937, which can be regarded as privacy information. Of course, you can erase any relation as you like.

Plot Figures

Run 8_run_plot.sh. This command will plot two figures that visualize the results from 3_run_modify_activation.sh and 4_run_distant.sh.
