ai-msgbot GPT-2 M Conversational

A GPT-2 M 355M parameter model for usage with ai-msgbot to create a chatbot-like tool.

This model was fine-tuned on a parsed version of the Wizard of Wikipedia dataset for 10,000 steps. 20/24 layers were frozen for the fine-tuning process.

conversation data

The dataset was tokenized and fed to the model as a conversation between two speakers, whose names are below. this is relevant for writing prompts and filtering/extracting text from responses.

script_speaker_name = person alpha

script_responder_name = person beta

usage

in ai-msgbot

python ai_single_response.py --model GPT2_conversational_355M_WoW10k --prompt "hi! what are your hobbies?"

... generating...

finished!

'i like to read.'

examples with Inference API

The model training (and the ai-msgbot scripts) "force" GPT-2 to generate text in a chat-like structure. If you want non-garbage outputs, these need to be specified manually:

person alpha:
hi! what are your hobbies?

then model will respond, ideally with person beta: "response text"

the default inference API examples should work okay
an ideal test would be explicitly adding person beta to the end of the prompt text. The model is forced to respond to the entered chat prompt instead of adding to the entered prompt and then responding to that (which may cut off the response text due to the Inference API limits).

The dialogues in the dataset reflect our daily communication way and cover various topics about our daily life. We also manually label the developed dataset with communication intention and emotion information. Then, we evaluate existing approaches on DailyDialog dataset and hope it benefit the research field of dialog systems. The dataset is available on \url{http://yanran.li/dailydialog}",
