FILTER: An Enhanced Fusion Method for Cross-lingual Language Understanding

This is the official repository of FILTER.

Requirements

We provide Docker image for easier reproduction. Please use dockers/Dockerfile or pull image directly.

docker pull studyfang/multilingual:xtreme

To run docker without sudo permission, please refer this documentation Manage Docker as a non-root user. Then, you could start docker, e.g.

docker run --gpus all -it -v /path/to/FILTER:/ssd -it studyfang/multilingual:xtreme bash

Quick Start

NOTE: Please make sure you have set up the environment correctly.

1. Download data and our models

Please set your DATA_ROOT in init.sh, and then run the following command to download specified task and its pretrained FILTER models.

bash scripts/download_data.sh ${task}

To download all tasks and its pretrained models, please run bash scripts/download_data.sh which may take a while.

2. Evaluate our pretrained models which are save in $DATA_ROOT/outputs/phase${idx}/${task} :

bash eval.sh -t ${task} -n phase${idx}/${task}

where

• idx could be 1 (without self-teaching) or 2(+ self-teaching).
• task is the name of the task to evaluate from ([xnli, pawsx, mlqa, tydiqa, xquad, udpos, panx])

Model Training

For QA model training, we use translated training data from XTREME team. Please refere to their repo or their translation directly. Once your data is ready, simply run the following command to train a FILTER model for supported XTREME tasks:

bash train.sh -t ${task} -n ${task}

To use different number of local and fusion layers, you can run this command:

bash train.sh -t ${task} -n ${task}_k${k}_m${m} -x "--filter_k ${k} --filter_m ${m}"

where

• task is the name of the task to train from ([xnli, pawsx, mlqa, tydiqa, xquad, udpos, panx])
• k is the number of fusion layers
• m is the number of local layers

The output model will be save into ${DATA_ROOT}/outputs/${task}_k${k}_m${m}.

Note that we ran experiments on 8 V100 GPUs for FILTER models. You may need to increase gradient_accumulation_steps if you have less GPUs.
