Unsupervised Online Grounding for Social Robots

Robots that incorporate social norms in their behaviors are seen as more supportive, friendly,and understanding. Since it is impossible to manually specify the most appropriate behavior for all possible situations, robots need to be able to learn it …

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 …

Enhancing Unsupervised Natural Language Grounding through Explicit Teaching

In this paper, a grounding framework is proposed that combines unsupervised and supervised grounding by extending an unsupervised grounding model with a mechanism to learn from explicit human teaching. To investigate whether explicit teaching …

A Cross-Situational Learning based Framework for Grounding of Synonyms in Human-Robot Interactions

Natural human-robot interaction requires robots to link words to objects and actions through grounding. Although grounding has been investigated in previous studies, not many considered grounding of synonyms and the majority of employed models only …

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, …

Evaluation of Word Representations in Grounding Natural Language Instructions through Computational Human-Robot Interaction

In order to interact with people in a natural way, a robot must be able to link words to objects and actions. Although previous studies in the literature have investigated grounding, they did not consider grounding of unknown synonyms. 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, …

A Probabilistic Framework for Comparing Syntactic and Semantic Grounding of Synonyms through Cross-Situational Learning

Natural human-robot interaction requires robots to link words to objects and actions through grounding. Although grounding has been investigated in previous studies, none of them considered grounding of synonyms. In this paper, we try to fill this …
