Many theories attempt to explain this ability of infant as imitation based on acoustic matching. However, the acoustic qualities of speech produced by the infant and...
Collaborative robots are quickly gaining momentum in real-world settings. This has motivated many new research questions in human-robot collaboration. In this paper, we address the questions of whether and when a robot should take initiative during joint human-robot task execution. We develop a system capable of autonomously tracking and performing table-top object manipulation tasks with humans and...
Goals are abstractions that express agents' intention and allow them to organize their behavior appropriately. How can agents develop such goals autonomously? This paper proposes a conceptual and computational account to this longstanding problem. We argue to consider goals as abstractions of lower-level intention mechanisms such as rewards and values, and point out that goals need to be considered...
