Results

This package achieves the state-of-art performance of 86.1% (single model), 89.4% (ensemble) on the CommonsenseQA leaderboard, surpassing the human performance of 88.9%.

Quickstart

1. pull docker:
   > docker pull yichongx/csqa:human_parity

2. run docker
   > nvidia-docker run -it --mount src='/',target=/workspace/,type=bind yichongx/csqa:human_parity /bin/bash
> cd /workspace/path/to/repo
   Please refer to the following link if you first use docker: https://docs.docker.com/

Features

Our code supports flexible training of various models on multiple choice QA.

• Distributed training with Pytorch native DDP or Deepspeed: see bash/task_train.sh
• Pause and resume training at any step; use option --continue_train
• Use any transformer encoders including ELECTRA, DeBERTa, ALBERT

Preprocessing data

Pre-processed data is located at data/.

We release codes for knowledge graph and dictionary external attention in preprocess/

1. Download data
   > cd preprocess
> bash download_data.sh
   
2. Add ConceptNet triples and Wiktionary definitions to data
   > python add_knowledge.py
   
3. We also add the most frequent relations in each question as a side information.
   > python add_freq_rel.py
   

Training and Prediction

1. train a model
   > bash bash/task_train.sh
2. make prediction
   > bash bash/task_predict.sh See task.py for available options.

Running codes for DEKCOR

The current code is mostly compatible to run DEKCOR. To run the original DEKCOR code, please checkout tag DEKCOR to use the previous version.
