## DialoGPT_AfriWOZ
This is a fine-tuned model of DialoGPT (small) on the AfriWOZ dataset. It is intended to be used as a conversational system in Wolof language.
The dataset it's trained on is limited in scope, as it covers only certain domains such as restaurants, hotel, taxi, and booking.
The perplexity achieved on the test and validation sets are 20.74 and 11.66, respectively.
* Generation example from an interactive environment:
|Role | Response |
|---------|------------|
|User | sowwu bi la bëg |
|Bot | waw, ndax mën ngan ma jox ay leeral si bërëb buñu feetee ak lekkukaay bi |
|User | soxla na dem gawu. ngir leeral rek bëg na joggee peterborough di dem cambridge |
|Bot | soxlu na dem ginaw jurrom ñenti waxtu ak ñaar fukki simili ak jurrom ben. |
|User | waw jiss sal ma ben bu seer si njëg si toluway |
|Bot | jënd bi baaxna. jerejef. ba benen yoon. |

### How to use
Now we are ready to try out how the model works as a chatting partner!
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
tokenizer = AutoTokenizer.from_pretrained("tosin/dialogpt_afriwoz_wolof")
model = AutoModelForCausalLM.from_pretrained("tosin/dialogpt_afriwoz_wolof")
# Let's chat for 5 lines
for step in range(5):
# encode the new user input, add the eos_token and return a tensor in Pytorch
new_user_input_ids = tokenizer.encode(input(">> User:") + tokenizer.eos_token, return_tensors='pt')
# append the new user input tokens to the chat history
bot_input_ids = torch.cat([chat_history_ids, new_user_input_ids], dim=-1) if step > 0 else new_user_input_ids
# generated a response while limiting the total chat history to 1000 tokens,
chat_history_ids = model.generate(bot_input_ids, max_length=1000, pad_token_id=tokenizer.eos_token_id)
# pretty print last ouput tokens from bot
print("DialoGPT_wolof_Bot: {}".format(tokenizer.decode(chat_history_ids[:, bot_input_ids.shape[-1]:][0], skip_special_tokens=True)))
