Few-shot Relation Extraction via Bayesian Meta-learning on Relation Graphs

Overview

Few-shot Relation Extraction via Bayesian Meta-learning on Relation Graphs

This is an implemetation of the paper Few-shot Relation Extraction via Bayesian Meta-learning on Relation Graphs.

Pretrain files

The codes rely on pre-trained BERT models. Please download pretrain.tar from Tsinghua Cloud and put it under the root. Then run tar xvf pretrain.tar to decompress it.

Usage

To run the model on the FewRel dataset, we could use the following command:

python train_demo.py --trainN 5 --N 5 --K 1 --Q 1 --model regrab --encoder bert --hidden_size 768 --val_step 1000 --batch_size 8 --fp16 --seed 1

Acknowledgement

Most of the codes are from the FewRel repo, which provides a neat codebase for few-shot relation extraction.
