Pragmatic Communication with Embodied Agents

Abstract

With the emergence of a new generation of embodied AI agents (e.g., cognitive robots), it has become increasingly important to empower these agents with the ability to learn and collaborate with humans through language communication. Despite recent advances, language communication in embodied AI still faces many challenges. Human language not only needs to ground to agents’ perception and action but also needs to facilitate collaboration between humans and agents. To address these challenges, I will introduce several efforts in my lab that study pragmatic communication with embodied agents. I will talk about how language use is shaped by shared experience and knowledge (i.e., common ground) and how collaborative effort is important to mediate perceptual differences and handle exceptions. I will discuss task learning by following language instructions and highlight the need for neuro-symbolic representations for situation awareness and transparency. I will further present explicit modeling of partners’ goals, beliefs, and abilities (i.e., theory of mind) and discuss its role in language communication for situated collaborative tasks.
