Question Translation Training for Better Multilingual Reasoning

📃 Paper | 🤗 Huggingface | 📭 Contact

⛰️ Overview

• This repository shares the code and models of our latest work on multilingual reasoning. In this work, we present a novel X-English question alignment finetuning step which performs targeted language alignment for best use of the LLMs English reasoning abilities.
• Utilizing this library, you can finetune open-source LLMs into strong multilingual reasoning systems. For example, our fine-tuned LLaMA2-7B/13B achieves superior multilingual performance, significantly outperforming baseline models of equivalent size.
• Overall, our method effectively reduces the performance disparity of LLMs across English and non-English languages, showing a new paradigm to unlock LLM’s capabilities to accompolish multilingual tasks.

📈 Benchmarks

Below we present LLMs' average answer accuracy (zero-shot) on multilingual reasoning benchmarks. With question alignment, our fine-tuned LLM surpasses the unaligned counterpart and the translate-training baseline (MathOctopus) by a large margin.

Our model has been open-sourced on Huggingface.

🧩 Installation

To install this repository, follow these steps:

git clone git@github.com:NJUNLP/QAlign.git
cd QAlign
pip install --editable ./

For detailed information about the conda environment, refer to the environment.yaml file.

🛠️ Training

We develope our training pipeline based on the stanford_alpaca repository.

To perform question alignment and response alignment on pre-trained LLMs, use the following command. Please note that you must replace $PROJECT_PATH with the appropriate paths in finetune.sh or finetune_dp.sh to ensure it is executable. When fine-tuning the 13B model, we utilize DeepSpeed to save memory. You can find our deepspeed configuration in the ./config/ds.json file.

• finetuning LLaMA2-7B

bash ./training_scripts/finetune_llama2_7B.sh

• finetuning LLaMA2-13B

bash ./training_scripts/finetune_llama2_13B.sh

📏 Evaluation

We use the evaluation code provided by Chen et al., which meansures answer accuracy by comparing the last numerical number that appears in the LLM-generated response with the gold answer.

To evaluate the model on mGSM and mSVAMP dataset, use the following command. Please note that you must replace $PROJECT_PATH and $MODEL_PATH with the appropriate paths in the script to ensure it is executable.

• evaluating with mGSM

cd evaluate/scripts

bash evaluate_mgsm.sh

• evaluating with mSVAMP

cd evaluate/scripts

bash evaluate_msvamp.sh
