Dialogue Engine for HRI

We have built a very simple, finite-state based dialogue manager to control interactions with the robot. In conjunction with a vector space model of language understanding, this model is effective for what it is.

However, we would like to experiment with and evaluate different models of dialogue. From frame-based approaches that are relatively common, to Augmented Transition Networks (ATNs) that can control both dialogue and actions, we’ll look at ways of giving the robot dialogue capability.

We can also explore using recent GPT models for casual dialogue.
