Modelling the Single Word to Multi-Word Transition Using Matrix Completion
2019
Infants acquire language in distinct stages, starting from single gestures and single words, and through utilising gestures, they learn multi-word combinations. To achieve this language development on artificial agents, we propose a multimodal computational model for single to multi-word transition through gesture-word combinations. Our approach relies on advancements in deep models for feature extraction and on casting the supplementary word generation problem into a matrix completion task. Experimental evaluation is carried out on a dataset recorded directly from the humanoid iCub's cameras, comprising the deictic gesture of pointing and real-world objects. Illustrated by our results, the proposed architecture further strengthens its potential to model early stage language acquisition.
