Title: User-centric dialog
Abstract: Some recent research has turned from being agent-centric to being user-centric. This paradigm shift is important if we are to create systems acceptable to the general population of users. In this talk we will begin with the reasoning behind user-centric research. Then we will look at concrete ways to apply this point of view to system training and to evaluation. Then we will address user-centric strategies when dealing with a malevolent user.

Title: Trustworthy Interactive Robots
Abstract: Trust is a multifaceted, complex phenomenon that is not well understood when it occurs between humans, let alone between humans and robots. Robots that portray social cues, including voice, gestures and facial expressions, are key tools in researching human-robot trust, specifically how trust is established, lost and regained. In this talk, I will discuss various aspects of trust for HRI including language, social cues, embodiment, transparency, mental models and theory of mind. I will present a number of studies performed in the context of two large projects: the UKRI Trustworthy Autonomous Systems Programme, specifically the Node on Trust; and the EPSRC ORCA Hub for robotic and autonomous systems for remote hazardous environments. This work will be contextualised around the new National Robotarium opening soon in Edinburgh.

Title: Alexa Prize and Beyond: the Future of Chatbot
Abstract: Developing a robust dialogue system for open-domain conversations is challenging because it is difficult to collect large data to train deep learning models that cover a variety of topics and there is no “ground truth” way of conducting open-domain conversations that satisfies a wide range of people. Even the evaluation of dialogue management is often subjective (thus, bias), which adds another level of difficulty to enhance open-domain dialogue systems. In this talk, I will first illustrate limitations of state-of-the-art dialogue systems using the latest transformer models as well as top-ranked bots from the Alexa Prize Socialbot Grand Challenge. I will then introduce our inference-driven dialogue management framework and discuss its extension to deep learning-based dialogue models. Finally, I will present real-life applications of open-domain dialogue management that we are currently working on regarding education and healthcare.
