# GPT2 trained on MultiWOZ.2.1
This repository provides all the necessary tools to perform response generation from an end-to-end system within
SpeechBrain. For a better experience, we encourage you to learn more about
[SpeechBrain](https://speechbrain.github.io). 
The performance of the model is the following:

| Release | Test PPL | Test BLEU 4 | GPUs |
|:-------------:|:--------------:|:--------------:| :--------:|
| 15.08.23 | 7.61 | 17.58 | 1xV100 32GB |

## Credits
The model is provided by [vitas.ai](https://www.vitas.ai/).

## Pipeline description
This dialouge system is composed of 2 different but linked blocks:

- Pretrained GPT Tokenizer that transforms words into subwords.
- GPT2LMHeadModel to generate the next sentence given the history of the dialogue.

The system is trained with dialogue from MultiWOZ corpus.


## Install SpeechBrain
First of all, please install SpeechBrain with the following command:

```
pip install speechbrain
```

Please notice that we encourage you to read our tutorials and learn more about
[SpeechBrain](https://speechbrain.github.io).

### Generating your Own Dialuge

```python
from speechbrain.pretrained import ResponseGenerator
res_gen_model = ResponseGenerator.from_hparams(source="speechbrain/MultiWOZ-GPT-Response_Generation", savedir="pretrained_models/MultiWOZ-GPT-Response_Generation", pymodule_file="custom.py")
res_gen_model.generate_response()
```

### Inference on GPU

To perform inference on the GPU, add  `run_opts={"device":"cuda"}`  when calling the `from_hparams` method.

## Parallel Inference on a Batch

Please, [see this Colab notebook](https://colab.research.google.com/drive/1hX5ZI9S4jHIjahFCZnhwwQmFoGAi3tmu?usp=sharing) to figure out how to transcribe in parallel a batch of input sentences using a pre-trained model.

### Training

The model was trained with SpeechBrain (986a2175).
To train it from scratch follows these steps:

1. Clone SpeechBrain:

```bash
git clone https://github.com/speechbrain/speechbrain/
```

2. Install it:

```
cd speechbrain
pip install -r requirements.txt
pip install -e .
```

3. Run Training:

```
cd recipes/MultiWOZ/response_generation
pip install -r extra_requirements.txt
python train_with_gpt.py hparams/train_gpt.yaml --data_folder=your_data_folder
```

You can find our training results (models, logs, etc) [here](https://www.dropbox.com/sh/vm8f5iavohr4zz9/AACrkOxXuxsrvJy4Cjpih9bQa?dl=0)

### Limitations

The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets.
