  # Tagalog DialoGPT
  A DialoGPT-medium model fine-tuned on Tagalog conversational data scraped from the web. This model is an output of a research on RoBERTa-based data augmentation for low resource languages. This is the baseline model which did not use any synthetic data in training. 
  
  #  Latest release: July 25, 2021
  * The model is currently only able to respond based on the history of 3 previous utterances before being limited. This is a result of the scarce amount of Tagalog conversations in our dataset. 
  
  # Dataset
  [PEx Conversations Dataset](https://huggingface.co/datasets/gabtan99/pex-conversations)
  
  # Usage
  Here is an example of using beam search for model inference.
  ```
  for step in range(2): 
      # 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
  
      # we limit the generation to 512 tokens, each utterance in training had a maximum of 128 tokens
      chat_history_ids = model.generate(
          bot_input_ids, max_length=512,
          pad_token_id=tokenizer.eos_token_id,
          num_beams=5, 
          no_repeat_ngram_size=3
      )
      
      # pretty print last ouput tokens from bot
      print("DialoGPT: {}".format(tokenizer.decode(chat_history_ids[:, bot_input_ids.shape[-1]:][0], skip_special_tokens=True)))
  ```
