NAACL 2022 Findings Paper: MWP-BERT: Numeracy-Augmented Pre-training for Math Word Problem Solving

Pre-training on Chinese dataset.

1. How to pre-train a MWP-BERT model:

python all_pretrain.py

1. How to pre-train a MWP-RoBERTa model:

python all_pretrain_roberta.py

Pre-training on English dataset.

1. How to pre-train a MWP-BERT model:

MWP-BERT on Chinese Dataset

Network Training

1. How to train the network on Math23k dataset only:

python math23k.py

2. How to train the network on Math23k dataset and Ape-clean jointly:

python math23k_wape.py

Weight Loading

To load the pre-trained MWP-BERT model or other pre-trained models in Huggingface, there are two lines of code need changing:

1. src/models.py, Line 232:

self.bert_rnn = BertModel.from_pretrained("hfl/chinese-bert-wwm-ext")

Load the model from your desired path.

2. src/models.py, Line 803/903/1039:

tokenizer = BertTokenizer.from_pretrained("hfl/chinese-bert-wwm-ext")

Load the tokenizer from your backbone model.

MWP-BERT on English Dataset

We build our implementation based on the code from https://github.com/zwx980624/mwp-cl, thanks for their contribution!

Network Training

1. How to train the network on MathQA dataset:

run mathqa.sh

Weight Loading

To load the pre-trained MWP-BERT model, just change:

mathqa.sh, Line 5:

--bert_pretrain_path pretrained_models/bert-base-uncased \

Load the pre-trained model from your desired path.
