Welcome to the official implementation of the paper "Mitigating Language-Level Performance Disparity in mPLMs via Teacher Language Selection and Cross-Lingual Self-Distillation" presented at NAACL 2024.

This repository demonstrates our proposed approach for addressing the language-level performance disparity issue in multilingual Pretrained Language Models (mPLMs). We introduce the ALSACE that comprises of Teacher Language Selection and Cross-lingual Self-Distillation to mitigate this issue.

With this code, you can:

• Train the mPLM with the ALSACE method
• Evaluate the language-level performance disparity of the mPLM

We conduct our experiment with Anaconda3. If you have installed Anaconda3, then create the environment for ALSACE:

conda create -n alsace python=3.8.5
conda activate alsace

After we setup basic conda environment, install required packages via:

pip install -r requirements.txt

bash run_script/finetuning.sh
bash run_script/distillation.sh
