The abstract of the paper is the following:
|
|
|
|
*Building open-domain chatbots is a challenging area for machine learning research. While prior work has shown that
|
|
scaling neural models in the number of parameters and the size of the data they are trained on gives improved results,
|
|
we show that other ingredients are important for a high-performing chatbot. Good conversation requires a number of
|
|
skills that an expert conversationalist blends in a seamless way: providing engaging talking points and listening to
|
|
their partners, and displaying knowledge, empathy and personality appropriately, while maintaining a consistent
|
|
persona. We show that large scale models can learn these skills when given appropriate training data and choice of
|
|
generation strategy. We build variants of these recipes with 90M, 2.7B and 9.4B parameter models, and make our models
|
|
and code publicly available. Human evaluations show our best models are superior to existing approaches in multi-turn
|
|
dialogue in terms of engagingness and humanness measurements. We then discuss the limitations of this work by analyzing
|
|
failure cases of our models.*
