Learning to Understand Non-Categorical Physical Language for Human Robot Interactions

摘要

Learning the meaning of language with respect to the physical world in which a robot operates is a necessary step for shared autonomy systems in which natural language is part of a user-specific, customizable interface. We propose a learning system in which language is grounded in visual percepts without pre-defined category constraints by combining CNNbased visual identification with natural language labels, moving towards making it possible for people to use language as a highlevel control system for low-level world interactions, allowing a system to operate on shared visual/linguistic embeddings. We evaluate the efficacy of this learning by evaluating against a wellknown object dataset, and report preliminary results that outline the feasibility of pursuing a visual feature approach to domainfree language understanding.
