This is the implementation of the paper Meta Self-training for Few-shot Neural Sequence Labeling. MetaST is short for meta-learning for self-training.

In this work we present MetaST, a self-training framework with auto data selection technique to prevent error probagation. You can find more details of this work in our paper.

1. create a conda environment running Python 3.6:

conda create --name MetaST python=3.6
conda activate MetaST

2. install the required dependencies:

pip install -r requirements.txt

1. Pull docker
   

docker pull yaqing/pytorch-meta-st:v0.3

2. Run docker
   

docker run -it --rm --runtime nvidia  yaqing/pytorch-meta-st:v0.3 bash

Please refer to the following link if you first use docker: https://docs.docker.com/

Training on SNIPS
> bash ./scripts/run_snips.sh

Note that we ran experiments on V100 GPU (32GB) for base MetaST models. You may need to reduce batch size for other GPUs.

1. BERT: BERT-based classifier

We will soon add more language model families.

The implementation is based on https://github.com/huggingface/transformers
We also used some code from: https://github.com/cliang1453/BOND
