This repository provides the implementation details for the ACL 2021 main conference paper:
**BoB: BERT Over BERT for Training Persona-based Dialogue Models from Limited Personalized Data**. [[paper]](https://aclanthology.org/2021.acl-long.14/)
## 1. Data Preparation
In this work, we carried out persona-based dialogue generation experiments under a persona-dense scenario (English **PersonaChat**) and a persona-sparse scenario (Chinese **PersonalDialog**), with the assistance of a series of auxiliary inference datasets. Here we summarize the key information of these datasets and provide the links to download these datasets if they are directly accessible.
* **For Persona-Dense Experiments**
| Dataset | Type | Language | Usage | Where to Download |
| ---- | ---- | ---- | ---- | ---- |

* **Download Pre-trained BERT**
The BoB model is initialized from public BERT checkpoints:
* **English BERT**: [https://huggingface.co/bert-base-uncased/tree/main](https://huggingface.co/bert-base-uncased/tree/main)
* **Chinese BERT**: [https://huggingface.co/bert-base-chinese/tree/main](https://huggingface.co/bert-base-chinese/tree/main)
## 2. How to Run
The `setup.sh` script contains the necessary dependencies to run this project. Simply run `./setup.sh` would install these dependencies. Here
we take the English PersonaChat dataset as an example to illustrate how to run the dialogue generation experiments. Generally, there are three steps, i.e., **tokenization**, **training** and **inference**:
* **Preprocessing**
```
python preprocess.py --dataset_type convai2 \
--trainset ./data/ConvAI2/train_self_original_no_cands.txt \
--testset ./data/ConvAI2/valid_self_original_no_cands.txt \
--nliset ./data/ConvAI2/ \
--encoder_model_name_or_path ./pretrained_models/bert/bert-base-uncased/ \
--max_source_length 64 \
--max_target_length 32
```
We have provided some data examples (dozens of lines) at the `./data` directory to show the data format. `preprocess.py` reads different datasets and tokenizes the raw data into a series of vocab IDs to facilitate model training. The `--dataset_type` could be either `convai2` (for English PersonaChat) or `ecdt2019` (for Chinese PersonalDialog). Finally, the tokenized data will be saved as a series of JSON files.
* **Model Training**
```
CUDA_VISIBLE_DEVICES=0 python bertoverbert.py --do_train \
--encoder_model ./pretrained_models/bert/bert-base-uncased/ \
--decoder_model ./pretrained_models/bert/bert-base-uncased/ \
--decoder2_model ./pretrained_models/bert/bert-base-uncased/ \
--save_model_path checkpoints/ConvAI2/bertoverbert --dataset_type convai2 \
--dumped_token ./data/ConvAI2/convai2_tokenized/ \
--learning_rate 7e-6 \
--batch_size 32
```
Here we initialize encoder and both decoders from the same downloaded BERT checkpoint. And more parameter settings could be found at `bertoverbert.py`.
* **Evaluations**
```
CUDA_VISIBLE_DEVICES=0 python bertoverbert.py --dumped_token ./data/ConvAI2/convai2_tokenized/ \
--dataset_type convai2 \
--encoder_model ./pretrained_models/bert/bert-base-uncased/ \
--do_evaluation --do_predict \
--eval_epoch 7
```
Empirically, in the PersonaChat experiment with default hyperparameter settings, the best-performing checkpoint should be found between epoch 5 and epoch 9. If the training procedure goes fine, there should be some results like:
```
Perplexity on test set is 21.037 and 7.813.
```
where `21.037` is the ppl from the first decoder and `7.813` is the final ppl from the second decoder. And the generated results is redirected to `test_result.tsv`, here is a generated example from the above checkpoint:
```
persona:i'm terrified of scorpions. i am employed by the us postal service. i've a german shepherd named barnaby. my father drove a car for nascar.
query:sorry to hear that. my dad is an army soldier.
gold:i thank him for his service.
response_from_d1:that's cool. i'm a train driver.
response_from_d2:that's cool. i'm a bit of a canadian who works for america.
```
where `d1` and `d2` are the two BERT decoders, respectively.
* **Computing Infrastructure:**
* The released codes were tested on **NVIDIA Tesla V100 32G** and **NVIDIA PCIe A100 40G** GPUs. Notice that with a `batch_size=32`, the BoB model will need at least 20Gb GPU resources for training.
