ai-msgbot GPT2-L + daily dialogues

NOTE: this model card is a WIP

GPT2-L (774M parameters) fine-tuned on the Wizard of Wikipedia dataset for 40k steps with 34/36 layers frozen using aitextgen. This model was then subsequently further fine-tuned on the Daily Dialogues dataset for an additional 40k steps, this time with 35 of 36 layers frozen.

Designed for use with ai-msgbot to create an open-ended chatbot (of course, if other use cases arise, have at it).

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

examples

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).

Example prompt:

do you like to eat beans? 
person beta:

Resulting output

do you like to eat beans? 

person beta:
no, i don't like

    abstract = "We develop a high-quality multi-turn dialog dataset, \textbf{DailyDialog}, which is intriguing in several aspects. The language is human-written and less noisy. 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}",
