Unsupervised Online Grounding of Natural Language during Human-Robot Interaction

Allowing humans to communicate through natural language with robots requires connections between words and percepts. The process of creating these connections is called symbol grounding and has been studied for nearly three decades. Although many …

Enhancing Unsupervised Language Grounding through Online Learning

To enable natural human-robot collaboration robots need to understand natural language, which in turn requires mechanisms to ground language by connecting words to corresponding percepts. This paper, presents an unsupervised online grounding …

Action Learning and Grounding in Simulated Human Robot Interactions

Natural human-robot interaction requires robots to learn new tasks autonomously and link the learned actions to their corresponding words through grounding. Previous studies focused only on action learning or grounding, but not both. In this paper, …

Simultaneous Action Learning and Grounding through Reinforcement and Cross-Situational Learning

Natural human-robot interaction requires robots to learn new tasks autonomously and link the learned actions to their corresponding words through grounding. Previous studies focused only on action learning or grounding, but not both. In this paper, …
