Hopping Too Late: Exploring the Limitations of Large Language Models on Multi-Hop Queries

This repository contains the official code of the paper Hopping Too Late: Exploring the Limitations of Large Language Models on Multi-Hop Queries presented at EMNLP 2024.

Setup

The benchmark creation and all experiments and evaluations were conducted in a Python 3.9 environment. To clone the repository and set up the environment, please run the following commands:

git clone https://github.com/edenbiran/HoppingTooLate.git
cd HoppingTooLate
pip install -r requirements.txt

Dataset

The dataset created for this work is available in data/two_hop.csv.

Creating the dataset can be done using src/create_dataset.py and evaluating a model on the dataset on can be done using src/evaluate_dataset.py.

Experiments

The experiments in the paper can be reproduced using the following scripts: - src/generate_entity_description.py - The Patchscopes entity description experiments. - src/patch_activations.py - The back-patching experiments. - src/project_sublayer.py - The sublayer Projection experiments. - src/knockout_attention.py - The attention knockout experiments.

Results

Classifying the experiments results can be done using src/classify_results.py and analyzing the classified results can be done using src/analyze_results.py.
