Our most engaging model, which controls both repetition and question-asking -marked 'Question (CT)' in Figure 3 (left) -matches the engagingness of the winning entry in the ConvAI2 competition, as both models achieve a raw score 7 of 3.1 (Dinan et al., 2019).
the Con-vAI2 winner, Lost in Conversation, was trained on approximately 12× as much data as our model.
