A recent trend is to produce personalized responses by conditioning the generation on a persona profile to make the response more consistent through the dialogue (Li et al., 2016b).
personaChat (Zhang et al., 2018b;Kulikov et al., 2018) dataset was created, and then extended in ConvAI 2 challenge (Dinan et al., 2019), to show that by adding persona information as input to the model, the produced responses elicit more consistent personas.
