Base model: microsoft/DialoGPT-large

Fine tuned for dialogue response generation on the Persuasion For Good Dataset (Wang et al., 2019)

Three additional special tokens were added during the fine-tuning process:

• <|pad|> padding token
• <|user|> speaker control token to prompt user responses
• <|system|> speaker control token to prompt system responses

The following Dialogues were excluded:

• Those with donation amounts outside of the task range of [$0, $2].
• Those where a donation of 0 was made at the end of the task but a non-zero amount was pledged in the dialogue.
• Those with more than 800 words.

Stats:

• Training set: 519 dialogues
• Validation set: 58 dialogues
• ~20 utterances per dialogue
