When Life Gives You Lemons, Make Cherryade: Converting Feedback from Bad Responses into Good Labels

28 Oct 2022  ·  Weiyan Shi, Emily Dinan, Kurt Shuster, Jason Weston, Jing Xu ·

Deployed dialogue agents have the potential to integrate human feedback to continuously improve themselves. However, humans may not always provide explicit signals when the chatbot makes mistakes during interactions. In this work, we propose Juicer, a framework to make use of both binary and free-form textual human feedback. It works by: (i) extending sparse binary feedback by training a satisfaction classifier to label the unlabeled data; and (ii) training a reply corrector to map the bad replies to good ones. We find that augmenting training with model-corrected replies improves the final dialogue model, and we can further improve performance by using both positive and negative replies through the recently proposed Director model.
