Impact of Tutoring Strategies in Grounded Lexicon Learning

摘要

This paper investigates the role of tutor feedback in grounded language learning experiments. We compare two dominant paradigms in language learning: interactive learning and cross-situational learning using robot-robot experiments in the real world. In particular, we study a mixed paradigm, introduced in earlier work, only now in real world interaction. Our experiments quantify the potential impact of social feedback in language learning. Since the grounded world is a more structured environment than random worlds, we also quantify whether algorithms can make use of that structure.
